<P> The new NCAA rule was passed in response to the end of the 4th quarter in the 2010 Music City Bowl . In that game, the North Carolina Tar Heels were down 20 - 17 at the end of the 4th quarter and because they had no timeouts, they spiked the ball to stop the clock with 1 second left while too many men were on the field due to confusion about whether the field goal unit needed to come on the field . Because college football did not yet have the 10 - second runoff, UNC was penalized 5 yards but was still able to kick the field goal to send the game to overtime, and would wind up beating Tennessee 30 - 27 in double overtime . Ironically, the new rule would not have saved Tennessee, because the Tar Heels' foul came after the snap, which would not have triggered the runoff . </P> <P> In the NFL, most defensive penalties result in an automatic first down . The exceptions are offside, encroachment, neutral zone infraction, delay of game, illegal substitution, calling excess timeouts, running into a kicker, and having more than 11 men on the field . In these cases, the appropriate yardage penalty is assessed . If the yardage penalty results in a first down, then a new set of downs is awarded; otherwise, there is a repeat of down . </P> <Table> <Tr> <Th> Foul </Th> <Th> Description </Th> <Th> Signal </Th> <Th_colspan="4"> Penalty Yardage </Th> </Tr> <Tr> <Th> NFL </Th> <Th> NCAA </Th> <Th> HS </Th> <Th> CFL </Th> </Tr> <Tr> <Td> Blocking below the waist </Td> <Td> An illegal block, from any direction, below the waist by any defensive player or by an offensive player under certain situations, by any player after change of possession, by any player in high school with certain exceptions .

This happens most often in the last two minutes of a half when the offense is trying to go down the field in a hurry .

This is most often seen on an onside kick where a member of the kicking team prematurely comes in contact with the ball in an attempt to recover it . Like illegal touching of a forward pass, if a defender (member of the receiving team) first touches the ball, any player may touch it .

Ineligible receivers must wait until the pass is thrown beyond the line of scrimmage (or touched) before moving past the line of scrimmage .

Not assessed if the ball is spiked . If the quarterback has moved outside of the area between his offensive tackles (the "tackle box" or more commonly called "the pocket"), there is no foul for grounding the ball if the quarterback throws the ball past the line of scrimmage . High school is more restrictive: spiking the ball is only allowed if the quarterback is under center, and the quarterback may not legally throw the ball away when outside the "tackle box ." </Td> <Td> Both hands held out flat, facing each other, in front of the referee, moving down together diagonally roughly from one shoulder to the opposite hip . </Td> <Td> 10 yards or spot of foul, whichever is farther from the original line of scrimmage, and loss of down .

This foul occurs simultaneously with the snap . Unlike offensive players, defensive players are not compelled to come to a set position before the snap . If a defender jumps across the line but gets back to his side before the snap, there is no foul . In the case of an offside foul, play is not stopped, and the foul is announced at the conclusion of the play . Media covering the games call it a "free play" for the offense, as the non-offending team may decline the penalty and take the yardage gained on the play (and when the play works against them, like a turnover to the opposing team, the non-offending team can accept the penalty and retake possession of the ball) - unlike in the case of a false start foul against the offense, whereupon the play is immediately stopped by the officials . This foul is almost always committed by the defense (any offensive player that moves into the neutral zone after setting would be charged with a false start). However, it is possible for the offense to commit this foul . If an offensive player lines up in the neutral zone, an offside foul will be called against the offense . </Td> <Td> Two hands placed on the hips </Td> <Td> 5 yards </Td> <Td> 5 yards </Td> <Td> Not applicable (see Encroachment) </Td> <Td> 5 yards </Td> </Tr> <Tr> <Td> Offside pass </Td> <Td> Any act to direct the ball forward (toward the opponent's dead / end line) other than a kick or a forward pass .

Beginning with the 2013 season, the down is replayed, unless the ball is beyond the line to gain after enforcement; the penalty no longer includes an automatic first down (defensive interference) or loss of down (offensive). If the interference is judged to be intentional, 15 additional yards . </Td> </Tr> <Tr> <Td> Personal foul (offense or defense) (Major foul in Canada) </Td> <Td> A conduct - or safety - related infraction .

If the officials decide that the action was particularly flagrant, the player, coach or spectator in question may be ejected from the game .
