TOSS OF COIN. Not more than three minutes before the kickoff of the first half, the Referee, in the presence of the captains of both teams (limit of six per team, active, inactive or honorary), shall toss a coin at the center of the field. Prior to the Referee’s toss, the call of “heads” or “tails” must be made by the captain of the visiting team, or by the captain designated by the Referee if there is no home team. Unless the winner of the toss defers his choice to the second half, he must choose one of two privileges, and the loser is given the other. The two privileges are:
(a) The opportunity to receive the kickoff, or to kick off; or
(b) The choice of goal his team will defend. If the coin does not turn over in the air or the toss is compromised in any way, the Referee shall toss it again. The captain’s original call may not be changed.
Penalty: For failure to comply: Loss of coin-toss option for both halves and overtime, and loss of 15 yards from the spot of the kickoff for the first half. For the second half, the captain who lost the pregame toss is to have the first choice of the two privileges listed in (a) or (b), unless one of the teams lost its first and second half options, or unless the winner of the pregame toss deferred his choice to the second half, in which case he must choose (a) or (b) above. Immediately prior to the start of the second half, the captains of both teams must inform the Referee of their respective choices. A captain’s first choice from any alternative privileges listed above is final and not subject to change.

Section 5: TIMEOUTS
4-5-1
PDF page 19-19
CHARGED TEAM TIMEOUTS. The Referee shall suspend play while the ball is dead and declare a charged team timeout upon the request for a timeout by the head coach or any player (not a substitute) to any official. If an assistant coach signals for a timeout and it is inadvertently granted, the timeout will stand.
Item 1. Timeouts Allowed. A team is allowed three charged team timeouts during each half and two timeouts during an overtime period in the regular season. The Referee or another game official will notify the head coach when he has exhausted his permitted timeouts in a half or overtime period. Any request for additional timeouts should be ignored.
Item 2. Length of Timeouts. Charged team timeouts shall be two minutes in length unless the timeout is not used by television for a commercial break. Timeouts shall be 30 seconds in length when the designated number of television commercials has been exhausted in a quarter, if it is a second charged team timeout in the same dead ball period, or when the Referee so indicates.
Item 3. Consecutive Team Timeouts. Each team may be granted a charged team timeout during the same dead ball period, but a second charged team timeout by either team during the same dead ball period is prohibited. Such consecutive charged team timeouts may follow a Referee’s timeout, or any automatic or other administrative timeouts, provided it is not an excess team timeout after a team has exhausted all its permitted timeouts, or a second timeout called in an attempt to “freeze” a kicker per Item 4 and Rule 12-3-1-v.
Penalty: For when a team requests and is granted a second timeout during the same dead ball period, or a timeout after exhausting its permitted timeouts: Loss of five yards for delay of game and the timeout is charged. If the timeout is by the offense while time is in after the two-minute warning, a 10-second runoff option is available, in which case, the play clock will be reset to 30 seconds. If the timeout is by the defense while time is in, the play clock is reset to 40 seconds. If time is in, the game clock will start with the ready for play signal unless the offense chooses to have the clock start on the snap.
Item 4. Unsportsmanlike Conduct. An attempt to call an excess team timeout, or to call a second timeout in the same dead ball period, by Team B in an attempt to “freeze” a kicker prior to a field goal or Try kick attempt shall be ignored and is unsportsmanlike conduct regardless of whether a timeout is granted (see 12-3-1-v). The timeout will be charged if granted.

INJURY TIMEOUTS PRIOR TO TWO-MINUTE WARNING OF EITHER HALF. When an injury timeout is called, the injured player must leave the game for the completion of one down. The player will be permitted to remain in the game if:
(a) either team calls a charged team timeout;
(b) the injury is the result of a foul by an opponent; or
(c) the period ends, or the two-minute warning occurs before the next snap. At the conclusion of an injury timeout, the game clock will start as if the injury timeout had not occurred. If either team takes or is charged with a timeout, the clock will start on the snap.
4-5-4
PDF page 20-20
INJURY TIMEOUTS AFTER TWO-MINUTE WARNING OF EITHER HALF. After the two-minute warning of a half, the following shall apply:
(a) If a team has not used its three charged team timeouts, the team of the injured player will be charged a team timeout, unless:
(1) the injury is the result of a foul by an opponent; or
(2) the injury occurs during a down in which there is a change of possession, a touchdown, a safety, a successful field goal, a free kick, or an attempted Try.
(b) If a team has used its three charged team timeouts, an excess team timeout shall be called by the Referee, unless:
(1) the injury is the result of a foul by an opponent; or
(2) the injury occurs during a down in which there is a change of possession, a touchdown, a safety, a successful field goal, a free kick, or an attempted Try.
(c) The player must leave the game for the completion of one down, unless:
(1) the injury is the result of a foul by an opponent; or
(2) either team calls or is charged a team timeout other than an excess timeout.
Penalty: For the second and each subsequent excess team timeout after the two-minute warning: Loss of five yards from the succeeding spot for delay of the game. Notes:
(1) No yardage penalty will be assessed for the first excess team timeout, but a 10-second runoff of the game clock may be applicable pursuant to Note 3 below. At the conclusion of an excess timeout taken while time is in, the game clock shall start with the ready for play signal, unless the opponent chooses to have the clock start on the snap. For any excess timeout charged to the defense, the play clock is reset to 40 seconds. For any excess timeout charged to the offense, the play clock is reset to 25 seconds unless a 10-second runoff is applicable (see Note 3).
(2) If the Referee has already called an excess team timeout in that half for a team, any subsequent excess timeout for that team will result in a five-yard penalty, and a 10-second runoff of the game clock may be applicable pursuant to Note 3 below. (A penalty for a fifth and subsequent excess timeout for injury shall be considered a foul between downs and will not offset a foul or be part of a multiple foul (see 14-1-2-Item 4-Exc).
(3) If an excess team timeout is charged against a team in possession of the ball, and the timeout causes the clock to stop or delays the clock from starting on the ready for play signal, the ball shall not be put in play until the time on the game clock has been reduced by 10 seconds, if the defense so chooses, the play clock reset to 30 seconds, and the game clock shall start with the ready for play.
(4) Either half can end as the result of the 10-second runoff referenced above.
(5) If an injury timeout is called for both teams during or after a down, charged team timeouts and/or excess team timeouts are charged as appropriate, but no yardage or 10-second runoff penalties shall be enforced.
(6) If a foul by either team occurs during a down in which there is also an injury, such foul does not affect the charging of an excess timeout, but it does prevent a 10-second runoff that may result from the excess timeout, because the foul stopped the clock.
(7) If a dead ball foul by either team occurs after a play in which there is also an injury to the opposing team, such foul does not affect the charging of an excess timeout, but it does prevent a 10-second runoff or 40-second play clock reset that may result from the excess timeout.
(8) The Competition Committee deprecates feigning injuries, with subsequent withdrawal, to obtain a timeout without penalty. Coaches are urged to cooperate in discouraging this practice.

(b) when there is an undue pileup on the runner, or while determining possession after a fumble while time is in;
(c) when there is an undue delay by officials in spotting the ball for the next snap;
(d) if the snap is made before the officials can assume their positions (see 4-6-5-b if it is a repeated act);
(e) when there is an injury to an official or member of the chain crew;
(f) during an officials’ conference; or
(g) while repairing or replacing game equipment, except player equipment. After a Referee’s timeout, the time remaining on the play clock shall be the same as when it was stopped. The play clock and the game clock will start as if the Referee’s timeout had not occurred.

INTERRUPTION OF PLAY CLOCK. If the play clock is stopped prior to the snap for any reason, after the stoppage has concluded, the time remaining on the play clock shall be the same as when it stopped, unless:
(a) the stoppage has been for: (1) a charged team timeout; (2) the two-minute warning; (3) the expiration of a period; (4) replay administration pursuant to Rule 15-9 with fewer than 25 seconds on the play clock; (5) a penalty enforcement other than for an action that conserves time; (6) an excess timeout that is charged to the offense that does not result in a 10-second runoff; or (7) an excess timeout charged to both teams during the same down. For 1-7, above, the play clock shall be reset to 25 seconds unless another rule requires otherwise;
(b) the stoppage has been for (1) an Instant Replay review that results in a reversal that does not result in a 10-second runoff or a team timeout; (2) a live ball foul that is subsequently nullified after crew conference and does not result in a 10-second runoff; (3) an excess timeout that is charged to the defense; or (4) a penalty enforcement for a defensive foul that conserves time. For 1-4, above, the play clock shall be reset to 40 seconds, unless another rule requires otherwise;
(c) the stoppage results in a 10-second runoff from the game clock, in which case the play clock shall be reset to 30 seconds; or
(d) fewer than 10 seconds remain on the play clock at the time of the stoppage, in which case it shall be reset to 10 seconds, or the exact time remaining on the play clock at the discretion of the Referee.

OTHER DELAY OF GAME FOULS. Other examples of action or inaction that are to be construed as delay of the game include, but are not limited to:
(a) a player unnecessarily remains on a dead ball or on a runner who has been downed;
(b) the snapper repeatedly snaps the ball after the neutral zone is established and before all the officials have had a reasonable time to assume their normal officiating positions (see 7-6-3-c);
(c) undue delay by either team in assembling after a timeout;
(d) a defensive player aligned in a stationary position within one yard of the line of scrimmage makes quick and abrupt actions that are not part of normal defensive player movement and are an obvious attempt to cause an offensive player(s) to foul (false start). The officials shall blow their whistles immediately. If the defender is walking or running toward the line of scrimmage in an effort to time the snap, but stops abruptly because the snap is not made, it is not a foul for delay of game;
(e) spiking or throwing the ball in the field of play after a down has ended, except after a score;
(f) intentional contact with the football or a player to delay the snap or the officials’ ability to make the ball ready for play; or
(g) when a team requests and is granted a second timeout during the same dead ball period (unless Rule 4-5-1-Item 3 applies) or a timeout after exhausting its permitted timeouts. See 4-5-1 for penalty enforcement.
Penalty: For delay of the game: Loss of five yards:
(a) from the succeeding spot if it occurs between downs and the ball remains dead; or
(b) from the previous spot if the ball was in play.

Section 7: ACTIONS THAT CONSERVE TIME
4-7-1
PDF page 21-22
ILLEGAL ACTS. A team is not permitted to conserve time after the two-minute warning of either half by committing any of these acts:
(a) a foul by either team that stops the clock during any dead ball period;
(b) intentional grounding;
(c) an illegal forward pass;
(d) throwing a backward pass out of bounds;
(e) spiking or throwing the ball in the field of play after a down has ended, except after a touchdown; or
(f) illegally batting or kicking the ball out of bounds.
Penalty: For illegally conserving time: Loss of five yards unless a larger distance penalty is applicable.
Item 1. Actions by the Offense. When actions referred to above are committed by the offensive team while time is in, officials will run off 10 seconds from the game clock and reset the play clock to 30 seconds before permitting the ball to be put in play on the ready for play signal. The game clock will start on the ready for play signal unless another rule prescribes otherwise. If the offensive team has timeouts remaining, it will have the option of using a timeout in lieu of a 10-second runoff, in which case the game clock will start on the snap after the timeout. The defense always has the option to decline the 10-second runoff and have the yardage penalty enforced, but if the yardage penalty is declined, the 10-second runoff is also declined, the play clock is set to 25 seconds, and the clock starts on the snap.
Item 2. Actions by the Defense. If the action is by the defense, the play clock will be reset to 40 seconds, and the game clock will start on the ready signal, unless the offense chooses to have the clock start on the snap. If the defense has timeouts remaining, it will have the option of using a timeout in lieu of the game clock being started.

If a replay review after the two-minute warning of either half results in the on-field ruling being reversed or if a foul is called on either team while time is in and is subsequently nullified, and the correct ruling would not have stopped the game clock, or would have otherwise restarted the game clock before the next snap, the officials will run 10 seconds off the game clock and reset the play clock to 30 seconds before permitting the ball to be put in play on the ready for play signal. Neither team can decline the runoff, but either team can use a remaining timeout to prevent it.

BALL IN PLAY. If time expires at the end of any period while the ball is in play, the period continues until the down ends.

PDF page 22-22
PERIOD EXTENDED. A period may be extended for one untimed down, if any of the following occurs during a down during which time in the period expires, or during which the period had been extended pursuant to this Article:
(a) If there is a live ball foul by the defensive team that is accepted, the offensive team may choose to extend the period by an untimed down after enforcement of the penalty. If the first or third period is not so extended, any accepted penalty is enforced before the start of the succeeding period.
(b) If there is a foul by the offense, there shall be no extension of the period. If the foul occurs on the last play of the half, a score by the offense is not counted. However, the period may be extended for an untimed down, upon the request of the defense, if the offensive team’s foul or violation is for:
(1) illegal touching or first touching of a kick;
(2) kick catch interference or fair catch interference;
(3) a palpably unfair act;
(4) a personal or unsportsmanlike conduct foul committed during a down prior to a safety, an interception of a forward pass, the recovery of a backward pass or fumble, or the offensive team failing to reach the line to gain on fourth down; or
(5) a foul by the kicking team prior to a player of the receiving team securing possession of the ball during a down in which there is a scrimmage kick, or a free kick.
(c) If a touchdown is made on the last play of a period, the Try attempt shall be made (except during sudden-death overtime, or if a touchdown is scored during a down in which time in the fourth period expires and a successful Try would not affect the outcome of the game).
(d) If no fair catch signal is given and the kickers interfere with the receiver’s opportunity to catch a kick, the receiving team may extend the period by a down from scrimmage.
(e) If a fair catch is signaled and made, the receivers may choose to extend the period by a fair catch kick down (10-2-4). If the first or third period is not so extended, the receivers may start the succeeding period by either a down from scrimmage or fair catch kick (11-4-3).
(f) If a fair catch is signaled and the kickers interfere with a receiver’s opportunity to catch a kick, the receiving team may extend the period by either a down from scrimmage or a fair catch kick (10-2-4).
(g) If a safety results from a foul during the last play of a half, the score counts. A safety kick is made if requested by the receivers.
(h) If a double foul occurs during the last down of either half, the period shall be extended by an untimed down. Exceptions: The half is not extended if:
(1) both fouls are dead ball fouls;
(2) there is a major-minor double foul (“5 versus 15”), and the major foul is by the offense, or if the major foul is a dead ball foul by either team;
(3) the only foul by the defense is a dead ball foul (“clean hands end of half,” see 14-4-9-Exc. 3); or
(4) there is a double foul with a change of possession that does not involve a replay of the down (“clean hands,” see 14-5- 2). If a double foul occurs on the last play of the first or third periods, the period is not extended. If the first or third period is extended for any reason, or if a touchdown occurs during the last play of such a period, any additional play, including a Try attempt, shall be completed before the teams change goals. There may be more than one untimed down at the end of a period pursuant to this Article.
