Player Conduct Flashcards
INTERLOCKING INTERFERENCE
Fourth-and-10 on B20. On a successful field-goal attempt from the B28, guard A1 and tackle A2 grasp one another’s
arms to prevent rushing defenders from blocking the successful kick.
Ruling: Fourth-and-20 on the B30. Ten-yard penalty for interlocking interference upon contact with the opponent(s).
(12-1-4-b)
USE OF HANDS DURING LOOSE BALL—PERSONAL ATTEMPT TO RECOVER
Second-and-5 on 50. Runner A1 goes to the B40 where he fumbles. A2, in an attempt to recover the ball: (a) pushes
B2 in the back; or (b) grabs B2 from behind and pulls him out of the way, at the B40. A2 recovers the ball at the B38.
Rulings: In both (a) and (b), A’s ball, first-and-10 on B38. Legal play, since A2 is making a personal attempt to
recover a loose ball which he is eligible to touch.
USE OF HANDS—KICKING TEAM—PUNT
Fourth-and-10 on 50. A2, flanked wide on a punt, is double teamed by B1 and B2 as he moves five yards downfield.
A2 pulls B2 out of the way at B40, runs downfield, and makes the tackle on the punt return man B3 at B10. B3
fumbles and A3 recovers and is downed at the B15.
Ruling: A’s ball, first-and-10 at B15. A kicking team player may use his hands or arms to ward off, or push/pull an
opponent attempting to block him, but he may not pull the opponent to slingshot himself downfield.
HANDS TO THE FACE—DEFENSE—CLOSE-LINE PLAY
Second-and-10 on B40. A1’s pass falls incomplete. During the pass rush, B1 puts his hand on blocker A2’s facemask
and pushes A2’s head back. (a) A2’s head is pushed halfway back with force, and B1 maintains that position without
immediately releasing the head; or (b) A2’s head is pushed back slightly without force and B1’s hand slides off the
mask with little delay; or (c) B1 pins A2’s head all the way back, but does not maintain the position for any length of
time.
Rulings:
(a) First-and-10 on B35. Illegal hands to the face.
(b) Third-and-10 on B40. No foul.
(c) First-and-10 on B35. Illegal hands to the face.
Note: If the contact is direct and forcible, it is a foul, even without pinning the head back for a period of time. This
standard applies to both offensive and defensive players.
HANDS TO THE FACE—DEFENSE AGAINST WIDE RECEIVER
Second-and-10 on B40. B2 is playing wide receiver A2 tight at the line of scrimmage and immediately following the
snap: (a) B2 puts his hand on A2’s facemask and pushes A2’s head back, but immediately releases it; or (b) B2
delivers a blow to A2’s facemask or helmet with an open hand. A1’s pass is incomplete.
Rulings:
(a) First-and-10 on B35. Illegal hands to the face by B2 against the wide receiver. This is a foul regardless of
whether the play is a run or a pass. This same action by a defensive/offensive lineman against an opponent
would not be a foul in close-line play. (12-1-7)
(b) First-and-10 on B25. Unnecessary roughness.
DEFENSIVE HOLDING—PULL-AND-SHOOT
Fourth-and-7 on B16. At the snap, B1 grabs Tackle A5 at the line of scrimmage and pulls him back to the B14. This
allows B2 to shoot the gap in an attempt to block Kicker A1’s field goal attempt from the B24. However, (a) B2 stops
at the line of scrimmage and does not continue through the opening; or (b) B2 is blocked at the line scrimmage by
the wingback who slides over to block him. The field goal is good.
Rulings:
(a) Field goal is good. Kickoff A35. There is no foul for “pull-and-shoot” if no one attempts to “shoot.”
(b) A’s ball, first-and-10 on B11, or FG good KO A35. Defensive holding is called even if the “shooter” is blocked
by someone else. On a FG, there is no option for Team A to take the score and enforce the 5-yard penalty on
the kickoff, as there would be on a Try.
DEFENSIVE HOLDING—NOT TRIPPING
Second-and-9 on B45. A1 runs to the B41 where he is tackled. During the run, B2 reaches out and grabs blocker A2
by the ankle at the B43, causing A2 to go down.
Ruling: A’s ball, first-and-10 on B36. This is defensive holding, not tripping.
BLOCK IN THE BACK—INTO THE TACKLE
Fourth-and-10 on A40. A1’s punt is fielded by B1 at the B10, and during the return, B2 pushes A2 squarely in the
back at the B15, but the push actually pushes A2 into B1 at the B12 where he makes the tackle.
Ruling: B’s ball, first-and-10 on B6. This is a foul for a block in the back.
PASS BLOCKING—BLOCK IN THE BACK
Second-and-10 on B40. As quarterback A1 is in the pocket, lineman A2 is attempting to block defensive end B2. B2
gets completely past A2, and (a) A2; or (b) A3 (another lineman) pushes B2 directly in the back, pushing him past
A1. A1 then completes the pass for a touchdown.
Rulings: In both (a) and (b): Touchdown. This is a legal block because the contact occurred while the quarterback
was still in the pocket.
PASS BLOCKING—QB OUT OF THE POCKET—BLOCK IN THE BACK
Second-and-10 on B40. After quarterback A1 has scrambled out of the pocket, lineman A2 loses contact with
defensive end B2. B2 has an unrestricted path to A1, but A2 pushes B2 directly in the back, causing him to miss the
tackle. A1 passes to A2 for a touchdown.
Ruling: Second-and-20 on 50. The illegal block in the back should be called, because the quarterback was, (or had
been), out of the pocket.
BLOCK IN THE BACK—PUNT IN THE AIR—TEAM A OR B
Fourth-and-10 on 50. While A1’s punt is in the air: (a) B1 blocks flyer A2 in the back at the B18 and then B1 fair
catches the punt at the B12; (b) B1 blocks flyer A2 in the back at the B18 and then the untouched punt rolls into the
end zone; or (c) A3 blocks B4 in the back at the B40, after which the untouched punt rolls into the end zone.
Rulings:
(a) B’s ball, first-and-10 on B6. Post possession enforcement. (12-1-3-b)
(b) B’s ball, first-and-10 on B9. Since the ball is still alive at the time of the block, this is post-possession enforcement
from the spot of the foul, which is behind the end of the kick (B20).
(c) Fourth-and-20 on A40 or B’s ball, first-and-10 on B30.
OFFENSIVE HOLDING AT TIME OF TACKLE
As B1 is returning the opening kickoff, (a) B2 holds A2 as A2 is making the tackle at the B30; or (b) B2 holds A2 at
the B30, five yards away from the runner, as B1 is being tackled by A3 at the B35.
Rulings:
(a) B’s ball, first-and-10 on B35. No foul. Offensive Holding will not be called if the runner is being simultaneously
tackled by any defensive player.
(b) B’s ball, first-and-10 on B35. No foul.
TRIPPING OR LEG WHIP
Second-and-10 on B40. As QBA1 drops back to pass, blocker A2 is beaten by B2 on the pass rush. A2 falls to the
ground and (a) throws his leg out (no whipping motion); or (b) whips his leg around in an attempt to keep B2 from
sacking the quarterback. A2’s leg makes contact with B2 either above or below the knees. A1 runs to the B15.
Rulings:
(a) Second-and-20 on 50. Tripping. (12-1-8)
(b) Second-and-25 on A45. Unnecessary roughness (leg whip). In both situations, if there is a whipping motion, it
is a personal foul for a leg whip, regardless of where the contact occurs.
ILLEGALLY KICKING/BATTING THE BALL—POTENTIAL RUNOFF AFTER TWO-MINUTE WARNING
Third-and-5 at B40. There is 1:35 remaining in the fourth quarter, and Team B is ahead in the score, 22-20. QB A1
muffs a hand to hand snap, and while the ball is loose on the ground (a) at the B41, or (b) at the B38, A1 deliberately
kicks or bats it out of bounds at the B34.
Rulings: (a) and (b) Fourth-and-15 on 50. This is a foul during a fumble, so the enforcement spot is the spot of
the fumble. Since that spot is behind the line of scrimmage, the foul is enforced from the previous spot, with a loss
of down. In addition, Team B can elect a 10-second runoff and start the clock on the ready, as this was an intentional
foul that stopped the clock. It is a 10-yard penalty and a loss of down for Team A to illegally kick or bat the ball on a
scrimmage play.
Note: If the foul for illegal kicking or batting occurs beyond the line of scrimmage on a scrimmage kick play, the foul
is enforced as a foul on a scrimmage kick play, and there is no loss of down.
RUNNING/NOT RUNNING INTO KICKER—BALL TOUCHED BY B
Fourth-and-10 on A40. Team B puts a strong rush on the punter, and after B4 deflects the kick: (a) he runs into the
kicker; or (b) B5 runs into the kicker. The punt goes out of bounds at the B6.
Rulings:
(a) B’s ball, first-and-10 on B6. No foul.
(b) Fourth-and-5 on A45 or B’s ball, first-and-10 on B6 (decline). Since B5 did not touch the punt, he cannot run
into or rough the kicker.
NOT RUNNING INTO KICKER—BALL HITS GROUND
Fourth-and-4 on A40. Punter A1 muffs the snap at the A33 where it hits the ground. A1 recovers the ball at the A30,
and is run into by B1 while punting the ball. B2 recovers the ball at the B25.
Ruling: B’s ball, first-and-10 at B25. No foul. Once the ball hits the ground on a punt, there can be no roughing or
running into the kicker. Normal unnecessary roughness protection applies.
RUNNING INTO OR ROUGHING THE KICKER
Fourth-and 6 on A45. A1 punts the ball which goes out of bounds at the B10. B1, attempting to block the punt: (a)
brushes A1 with his right shoulder, but A1 remains upright; (b) hits A1’s kicking leg while it is extended, knocking A1
to the ground; (c) slides into A1’s plant leg, knocking him to the ground; (d) hits A1’s plant leg directly, knocking A1
to the ground; or (e) collides with A1 in the inner-thigh area or torso of his body, knocking A1 to the ground.
Rulings:
(a) B’s ball, first-and-10 on B10. No foul. There is no foul, if the contact with the kicker is incidental and minimal.
(b) Fourth-and-1 on 50, or B’s ball first-and-10 on B10. Running into the kicker.
(c) A’s ball, first-and-10 on B40. Roughing the kicker.
(d) A’s ball, first-and-10 on B40. Roughing the kicker.
(e) A’s ball, first-and-10 on B40. Roughing the kicker.
RUNNING/ROUGHING/UNNECESSARY ROUGHNESS—BALL SKIPS OFF GROUND
Fourth-and-3 on A45. The snap to punter A1 is low and skips off the ground once, but is fielded cleanly by A1, and
A1 is able to begin his normal punting motion. (a) B2 runs into A1 (not roughing); (b) B2 collides with A2 squarely in
the torso (normally enough for roughing); or (c) B2 throws a forearm into A2’s helmet. B2 does not block the punt.
The punt is shanked out of bounds on the B45.
Rulings:
(a) B’s ball, first-and-10 on B45. No foul for running into the kicker, since the snap hit the ground. (12-2-10-e)
(b) B’s ball, first-and-10 on B45. No foul for roughing the kicker, since the snap hit the ground. (12-2-10-e)
(c) A’s ball, first-and-10 on B40. Unnecessary roughness. If the snap touches the ground, only unnecessary
roughness protection applies, and if the contact is unnecessary roughness, it is a foul whether or not B2 touches
the punt.
CONTACT WITH KICKER—SECOND FOOT JUST HITS GROUND
Fourth-and-10 on B30. Field-goal kicker A1 kicks the ball at the B38 and his second foot just comes down to the
ground when: (a) B1 slides into A1 taking his feet out from under him and causing A1 to go to the ground; or (b) B1
bumps A1 on his feet causing A1 to stumble. The field goal is no good.
Rulings:
(a) A’s ball, first-and-10 on B15. Roughing the Kicker. (Running into the kicker is not an option when the second
foot has come back to the ground. If the contact is significant, this is roughing the kicker.)
(b) B’s ball, first-and-10 on B38 (the spot of the kick). No foul. Once the second foot has come back to the ground
the only potential fouls are roughing the kicker or unnecessary roughness.
ROUGHING/NOT ROUGHING THE HOLDER
Fourth-and-12 on B30. B2 leaves his feet in an attempt to block A1’s field goal attempt from the B38. He misses the
kick and: (a) lands in front of holder A2 and slides into him knocking him off his knees and to the ground; or (b)
makes slight contact with A2 and does not knock him over. The field goal is good.
Rulings:
(a) Field goal good, kickoff 50 or first-and-10 on B15 (take points off board). Roughing the holder.
(b) Field goal good, kickoff A35. No foul. There is no foul for running into the holder. Roughing is the only option
against the holder.
ROUGHING THE PASSER
Second-and-10 on B35. Quarterback A1 rolls out of the pocket, and while moving, completes a pass to A2 who runs
out of bounds at the B12. Just after A1 released the ball, B1 launches and hits A1 in the chest area with the hairline
part of the helmet and then continues to rip up and contact A1 under the chin with his helmet.
Ruling: A’s ball, first-and-goal on B6. Roughing the passer.
ROUGHING THE PASSER
Third-and-5 on 50. Quarterback A1, in the pocket, throws a pass to A2, who runs for a touchdown. Just after A1
released the ball, B1 lowers his head and hits A1 with the hairline part of his helmet in the chest area.
Ruling: Touchdown Team A, with the option to enforce the roughing the passer foul on the Try or the kickoff.
ROUGHING/NOT ROUGHING THE PASSER (NO PASS THROWN)
Second-and-10 on B35. Quarterback A1 drops back to pass, and while he is standing in the pocket at the B46, B1
tackles him from behind by (a) driving the crown of his helmet into the back of A1; (b) contacting A1’s head with his
forearm; (c) forcibly tackling A1 below the knees; or (d) diving and landing on the ground while swiping with his arm
and catching A1 around the calf. A1 lands on the ground at the B45.
Rulings:
(a), (b), and (c): First-and-10 on B20. Roughing the passer. (12-2-9)
(d) Third-and-20 on B45. No foul. Not forcible contact in the knee area or below.
ROUGHING THE PASSER—FUMBLE RECOVERED BY DEFENSE
Second-and-2 on B35. Quarterback A1 drops back to pass. B1 tackles him from behind by driving his lowered head
into the back of A1, contacting A1’s head with his forearm, or tackling A1 below the knees at the B44. As A1 is hit,
the ball leaves A1’s hand at the B45. The Referee correctly rules fumble. B2 recovers the ball at the B47.
Ruling: A’s ball, first-and-10 on B20. The quarterback was in a passing posture, so in each instance it is a foul for
roughing the passer.
ROUGHING THE PASSER—ILLEGAL FORWARD PASS
Second-and-10 at the 50. A1 scrambles, runs to the B49, retreats to the A45, and then passes the ball to A2 at the
B40. After the ball has left A1’s hand, B1 takes two steps and hits Quarterback A1 facemask-to-facemask as he
tackles him.
Ruling: Second-and-10 on 50. Roughing the Passer and Illegal Forward Pass This is not a 5 vs 15 because the IFP
foul carries a loss of down penalty, so the fouls offset at the previous spot. Roughing-the-passer rules apply on all
legal and illegal forward passes thrown from behind the line of scrimmage.
ACTION AGAINST QUARTERBACK WHEN PASS IS THROWN FROM BEYOND LINE
Second-and-10 on A20. Quarterback A1 drops back to pass but is chased out of the pocket and scrambles. At the
A21, believing he is still behind the line, A1 throws a pass to A2 who catches the ball and goes out of bounds at the
A35. Just as A1 releases the pass, B2: (a) B2 hits him helmet to helmet in an attempt to tackle him; (b) B2’s arm hits
A1’s helmet as B2 tries to tackle him; (c) B2 clubs A1 in the head as he attempts to make the tackle; or (d) B2 tackles
A1 below the knees.
Rulings:
(a) Second-and-10 on A20. Replay the down. This is unnecessary roughness and an illegal forward pass, but it is
not a 5 vs. 15, because the illegal forward pass beyond the line is not a simple 5.
(b) Third-and-14 on A16. This is not a foul by B2, because the passer is beyond the line. The illegal forward pass
is enforced from the spot of the foul with a loss of down.
(c) Second-and-10 on A20. Replay the down. The unnecessary roughness and illegal forward pass offset. (Not a 5
vs. 15).
(d) Third-and-14 on A16. This is not a foul by B2, because the passer is beyond the line. The illegal forward pass
is enforced from the spot of the foul with a loss of down.
TACKLING QUARTERBACK AT OR BELOW THE KNEES - SWIPE VERSUS WRAP
Second-and-10 on A40. QB A1 drops back in the pocket to pass. As B1 is rushing quarterback A1, he is blocked
and falls to the ground. B1 stays on the ground and crawls toward A1, and while still on the ground, tackles A1 at or
below the knees at the A30 by: (a) reaching out with one hand and swiping A1’s legs out from under him; or (b) by
reaching out and forcibly wrapping his arm around A1’s leg.
Rulings:
(a) Third-and-20 on A30. No foul.
(b) First-and-10 on B45. Roughing the passer.
NOT ROUGHING THE PASSER—EXTENDING ARMS
Second-and-10 on A40. B1 is rushing quarterback A1, and after A1 has released the pass, B1, who is within one
step of A1, pushes A1 to the ground. The pass falls incomplete.
Ruling: Third-and-10 on A40. No foul. If the action is late and clearly part of a second act after the pass is released,
it is a foul for roughing the passer.
ROUGHING THE PASSER—QUARTERBACK DUCKS
Second-and-10 on A20. A1 drops back to pass, and as he is about to be sacked in the pocket, he ducks his head to
avoid contact. Just as he ducks his head, B1, who is attempting to tackle him, forcibly hits A1: (a) helmet-to-helmet;
or (b) in the helmet with his right arm and takes him to the ground at the A15.
Rulings: (a) and (b) First-and-10 on A35. Roughing the passer. The onus is on the defender to avoid forcible contact
to the head of the quarterback
NOT ROUGHING THE PASSER—QUARTERBACK IS OUT OF THE POCKET
First-and-10 on A20. Quarterback A1 rolls out of the pocket, and while moving, throws an incomplete pass. Defender
B1 takes two steps after A1 released the ball and then tackles A1.
Ruling: Second-and-10 on A20. Not roughing the passer as the one-step rule is not in effect when the quarterback
is out of the pocket, unless the quarterback stops and sets up again in a passing position.
ROUGHING THE PASSER—LANDING ON QB WITH ALL OF DEFENDER’S BODY WEIGHT
First-and-10 on A30. QB A1 throws a pass from the pocket that falls incomplete, and B1 tackles him within one step
after the ball is released. B1 (a) makes a normal tackling motion without lifting or driving the QB into the ground, but
lands on him with his entire body weight or (b) lifts and slams the QB down but gets his body to the side of the QB.
Rulings: (a) and (b): First-and-10 on A45. Roughing the passer. The defender is prohibited from landing on the QB
with all or most of his body weight, even during a normal tackle. The defender is also prohibited from lifting and
driving the QB into the ground as he is making the tackle, even if he gets to the side of the QB when they land on
the ground.
CLIPPING IN CLOSE-LINE PLAY
First-and-10 on B40. Back A2 runs left and right tackle A5 blocks B5 below the waist (above the knees) from behind
at the line of scrimmage. B5 was lined up opposite the offensive center A6. A2 runs for a touchdown.
Ruling: A’s ball, first-and-25 on A45. Clipping by A5, since B5 was lined up more than one position removed and
was responding to the flow of the ball away from A5.
CLIPPING IN CLOSE-LINE PLAY—AT OR BELOW KNEES
First-and-10 on A40. On a running play, left guard A1 at the A42 hits nose tackle B2 below the knees from behind.
This action occurs as B2 is in pursuit of the runner. The runner is downed at the A47.
Ruling: A’s ball, first-and-23 on A27. Clipping. If A1’s block was above the knee would be a legal clip in this situation.
CLIPPING IN CLOSE-LINE PLAY—ROLL UP BLOCK
Second-and-3 on B48. Right guard A3 hits nose tackle B3 below the waist from behind as B3 is in pursuit of the
runner at the B49. A3 then rolls up on the back or side of the legs of B3.
Ruling: A’s ball, second-and-18 on A37. The initial block is legal, but the rolling-up action causes this to become a
foul for unnecessary roughness.
CLIPPING BY OFFENSIVE BACK
Second-and-4 on B14. QBA1 hands off to Back A2 at the B16. A2 runs around the right side to the B9. After the
snap, left wing back A3, (who was not flexed), blocks B4 from behind, below the waist but above the knees, at the
B16, behind the original position of the left guard.
Ruling: Second-and-19 on B29. Clipping. Blocking below the waist from behind is only legal, (subject to specific
limitations), in close line play by offensive linemen.
CRACKBACK—NOT FLEXED
Third-and-5 on A40. A2 is set one yard outside of tackle A3. At the snap, A2 goes towards the center and blocks B1
low from the side at the A42, toward the original spot of the snap. A4 runs to the A46.
Ruling: A’s ball, first-and-10 on A46. Legal block, since A2 was not flexed - he was lined up within two yards of
tackle A3. (12-2-2)
CRACKBACK—PLAYER IN MOTION—NOT FLEXED AT THE SNAP
Third-and-5 on A40. Slot-back A2, lined up on the right side of the formation, goes in motion toward the ball, and at
the snap, is behind the normal position of the right tight end. A2 blocks B3 below the waist at the A43. A2 runs out
of bounds at the A46.
Ruling: Third-and-17 on A28. Illegal crackback block. A man in motion is not permitted to crackback, even if he is
not flexed at the snap.
CRACKBACK—LOCATION OF BLOCK
First-and-10 on A30. Quarterback A1 runs to the A35 where he is downed. After the snap, wide receiver A3, who
was lined up six yards outside his tackle at the snap, came back in toward the ball and blocked B1 below the waist:
(a) at the A26; (b) at the A34; (c) at the A23; or (d) at the A33 beyond the original position of the ball.
Rulings:
(a) A’s ball, first-and-25 on A15. Illegal crackback.
(b) A’s ball, first-and-21 on A19. Illegal crackback.
(c) A’s ball, first-and-25 on A15. Illegal block below the waist because the block occurs outside the tight end box.
(d) A’s ball, second-and-5 on A35. This is not an illegal crackback block, because the blocker was moving away
from the original position of the ball when the block occurred.
CRACKBACK—PLAYER ORIGINALLY NOT FLEXED
Second-and-7 on A39. Quarterback A1 hands off to A3 who runs right and hands off to A4 who runs wide around
left end to the B40. Following the hand off, quarterback A1 becomes a lead blocker, turns the corner, (more than 2
yards outside the original position of the left tackle), and comes back toward where the ball was snapped, and blocks
tackle B7 low at the A40.
Ruling: Second-and-21 on A25. Illegal crackback block. This would also be an illegal block below the waist if the
block was outside the tight end box. The tight end box does not disappear when the ball leaves the box.
CRACKBACK—TIGHT END/WINGBACK—FLEXED/NOT FLEXED
Third-and-8 on 50. Prior to runner A2 sweeping around right end to the B40, A3, who is lined up on the right side of
the formation, dives back in toward the ball and blocks B1 below the waist at the 50. At the snap, A3 was located (a)
at tight end or wing back with his inside foot 1½ yards outside the right tackle’s outside foot; (b) at tight end or wing
back with his inside foot 2 yards outside the right tackle’s outside foot; (c) at tight end or wing back with his inside
foot 2½ yards outside the right tackle’s outside foot; or (d) at tight end with his inside foot 2 yards outside the right
tackle’s outside foot, but after the snap, he moves 3 yards outside and then blocks back toward the ball; or (e) at
wing back with his inside foot 2 yards outside the right tackle’s outside foot, but after the snap, he moves three yards
outside and then blocks back toward the ball.
Rulings:
(a) First-and-10 on B40. Legal block. Not flexed.
(b) First-and-10 on B40. Legal block. Not flexed.
(c) Third-and-23 on A35. Illegal crackback.
(d) First-and-10 on B40. Legal block. On the line of scrimmage and not flexed at the snap.
(e) Third-and-23 on A35. Illegal crackback, as A3 was in a backfield position at the snap.
CRACKBACK BLOCK
Third-and-5 on 50. A2 is lined up wide to the right on the line of scrimmage. A3 sweeps wide around the right side
and runs out of bounds at the B40. During the run, blocker A2 comes back toward the center of the field from the
50-yard line, and blocks defensive end B1 (a) low at the B46; (b) low at the B44; (c) with force to the head or neck
area at the B46, with his forearm, shoulder, or head (without lowering his head); (d) with force to the head or neck
area at the B44, with his forearm, shoulder, or head (without lowering his head); or (e) with force to the rib area at
the A44 with his forearm, shoulder, or head (without lowering his head).
Rulings:
(a) Third-and-16 on A39. Illegal crackback block (low) in the five-yard belt.
(b) Third-and-14 on A41. Illegal block below the waist outside of the tight end box.
(c) Third-and-16 on A39. Illegal crackback block (high) in the five-yard belt.
(d) First-and-10 on B40. Legal block, as it occurred more than 5 yards from the line of scrimmage in the direction
of Team B’s end line.
(e) Third-and-20 on A35. Blindside block. Although this action is not an illegal crackback, because it is not within
the 5-yard belt, it is parallel or back toward the blocker’s end line, so it is a blindside block.
Note: If a defender is in a position that protects him from an illegal crackback block, he is protected from blocks
below the waist, as well as forcible hits to the head or neck area by the defender, or hits to the body by the defender
with his head.
ILLEGAL CRACKBACK BLOCK
Third-and-10 on 50. A1 drops back to pass, but cannot find an open receiver, so he scrambles around the right side
and out of bounds at the B40. Tailback A2 had gone to the right for a swing pass, and as A1 scrambles to the right,
A2 comes back toward the middle of the field from the 50 and (a) blocks B1 low at the B46 behind the original
position of the tight end, or (b) blocks B1 to the head with the blocker’s head (not lowered), shoulder, or forearm at
the B46.
Rulings:
(a) A’s ball, third-and-21 on A39. Illegal crackback block.
(b) A’s ball, third-and-21 on A39. Illegal crackback block.
BLINDSIDE BLOCK / LEGAL BLOCK
A1’s punt is caught by B1 at the B20. B1 loops around toward the sideline, as A2 takes a pursuit angle to try and cut
B1 off. B2 is blocking for B1 and angles from the B35 to the B30, where he makes forcible contact with A2. (a) B2
contacts A2’s head with his head, shoulder or forearm; (b) B2 contacts A2’s shoulder or any part of his torso (above
the waist) with B2’s head, shoulder or forearm; (c) B2 pushes A2’s body or shoulder with his hands, not contacting
A2 with B2’s body; or (d) B2 steps in front of A2, screening him from getting to B1. B1 is tackled at the B40.
Rulings:
(a) B’s ball, first-and-10 on B15. Blindside block.
(b) B’s ball, first-and-10 on B15. Blindside block.
(c) B’s ball, first-and-10 on B40. Legal block.
(d) B’s ball, first-and-10 on B40. Legal block.
Note: It is a foul if a player initiates a block when his path is toward or parallel to his own end line and makes forcible
contact to his opponent with his helmet, forearm, or shoulder.
BLINDSIDE BLOCK— LEGAL / ILLEGAL BLOCK
Second-and-5 on A30. A2 takes a handoff from a QB under center or in shotgun position and runs off right tackle to
the A35. Left tackle A3 pulls and crosses to the right side of the formation, moving at an angle that is parallel to the
line of scrimmage, and kicks out left defensive tackle B2 while B2 is behind (a) the normal right tackle position, or
(b) the normal right tight end position. The block is to the body of B2, (below the neck and head area), with A3’s
head (not UOH), shoulder, or forearm.
Rulings:
(a) First-and-10 on A35. Legal block, because it occurred between the tackles and within 3 yards of either side the
line of scrimmage.
(b) Second-and-20 on A15. Blindside block, because the block occurred outside the normal position of the tackles.
Note: It is not a foul for a blindside block if the forcible contact occurs in “close line play” prior to the ball leaving that
area. The ball is not considered to have left that area if the player who takes the snap, either from a shotgun position
or from under center, retreats in the pocket immediately or with a slight delay, and hands the ball to another player,
or runs with the ball himself. This exception does not apply to any action other than a designed play. Any forcible
contact in “close line play” is still subject to the restrictions for crackback and peel back blocks.
BLINDSIDE BLOCK—BALL IN / OUT OF TACKLE TO TACKLE AREA
Second-and-10 on 50. QB A1 hands off to A2 who runs off right tackle to the B25. Immediately after the snap,
receiver A3, who was on the line of scrimmage and split 5 yards outside the right tackle at the snap, comes back
toward the ball and blocks nose guard B1 who had crossed the line of scrimmage and was at the A48 behind the
original position of the offensive right guard. The block is with force, shoulder to shoulder. (a) A1 was a T-quarterback,
or (b) A1 was in shotgun at the snap, 5 yards behind the line.
Ruling: In (a) and (b): First-and-10 on B25. Legal block because the block occurred in an area within 3 yards of the
line of scrimmage from tackle to tackle before the ball left that area. The ball is not considered to have left that area
due to a shotgun snap, so long as the ensuing action is a designed run play.
BLINDSIDE BLOCK / LEGAL BLOCK
Second-and-5 on A30. A2 takes a handoff from a shotgun or T-QB and starts to sweep around the right end. As he
is (a) behind the normal position of the right tackle, or (b) behind the normal position of the tight end, he stops and
changes direction toward the middle of the field. Left tackle A3 sees A2 change direction, runs toward him, and
forcibly blocks defensive end B2 at the A28 in the chest with his head (not UOH), forearm, or shoulder. The block
occurs behind the normal right guard position and is parallel to the line of scrimmage. A2 runs to the 50, where he
is tackled.
Rulings:
(a) First-and-10 on the 50. This is a legal block, as it occurred within the tackle to tackle area, within 3 yards of the
line of scrimmage, and before the ball left that area.
(b) Second-and-20 on A15. Blindside block. Although this block occurs within the tackle to tackle area, and within
3 yards of the line of scrimmage, the block occurred after the ball left that area.
Note: Once the ball leaves the tackle to tackle area within 3 yards of the line of scrimmage, the area disappears and
a block that satisfies the requirements of a blindside block is illegal even if the ball re-enters that area.
CRACKBACK—UNBALANCED FORMATION—FLEXED
First-and-10 on B25. Left tackle A3 lines up on the right side of the line, creating an unbalanced formation, with tight
end A2 lined up to the right of A3. Right tight end A2 then cracks back at the line of scrimmage. A1 runs around right
end to the B15.
Ruling: First-and-25 on B40. A2 is flexed and thus prohibited from cracking back.
LOW BLOCK IN THE PROCESS OF TACKLING/FAILING TO TACKLE RUNNER
Third-and-10 on B20. B1 intercepts A1’s pass on the B10 and returns it with blockers B2 and B3 directly in front of
B1. During the return, at the B40, A1 dives low in an attempt to tackle B1, and in the process: (a) goes through B2
below the waist before making the tackle at the B40; or (b) misses the tackle and then makes contact with B7 below
the waist. B1 runs out of bounds at the 50.
Rulings:
(a) B’s ball, first-and-10 on A45. Illegal low block.
(b) B’s ball, first-and-10 on 50. No foul.
Note: If A1 is attempting to make the tackle, he cannot go low through an opponent to get to the ball carrier. If, after
attempting to make a tackle, he accidentally makes contact with an opponent below the waist, it is not a foul for an
illegal low block.
LOW BLOCK TEAM B—PUNT
Fourth-and-2 on A45. Team A lines up in a punt formation. After the ball is kicked, flyer A4 is blocked below the waist
from the front by B4 at the 50. B1 fair catches the punt at the B14.
Ruling: B’s ball, first-and-10 on B7. Illegal low block by B4. The restriction on Team B begins at the snap. This is a
post-possession foul.
LOW BLOCK TEAM A—PUNT
Fourth-and-2 on A45. Team A lines up in a punt formation. Right guard A7 blocks B4 low (a) immediately after the
snap, or (b) after the punt. B1 fair catches the punt at the B14.
Rulings:
(a) B’s ball, first-and-10 on B14. No foul. Team A’s restriction against blocking low begins after the punt and the low
block occurs inside the tight end box.
(b) B’s ball, first-and-10 on B29 or A’s ball, fourth-and-17 on A30. Illegal low block after the punt.
Note: The restriction against blocking below the waist during a down in which there is a punt, begins after the snap
for Team B, but not until after the punt for Team A.
LOW BLOCK TEAM B—BLOCKED PUNT
Fourth-and-5 on 50. B1 blocks the punt which goes to the A34 where A2 attempts to recover. B2 blocks A2 below
the waist from the side at the A32 just prior to B1 recovering the ball and running to the A15, where he is downed.
Ruling: A’s ball, first-and-10 on B35. Blocking below the waist is prohibited by the receiving team during a down in
which there is a kick or change of possession. This is not a post-possession foul, because the kick did not cross the
line of scrimmage, so enforcement is from the previous spot with an automatic first down.
PUNT—TEAM B PUSHING TEAMMATE INTO OPPONENT
Fourth-and-20 on 50. Team A lines up a in punt formation. At the snap, B1 and B2 push down-lineman B3 into the
center in an attempt to block the punt. A2’s punt goes out of bounds at the B15.
Ruling: A’s ball, first-and-10 on B35. Team B cannot push a teammate into the offensive formation during a down
in which there is a scrimmage kick formation, and it is a foul whether there is a kick or not. This is not a post-possession foul, because it is an attempt to block the kick, so enforcement is from the previous spot with an automatic first down.
