These go into effect for the 2013 season ...
A player who targets and hits a defenseless player above the shoulders will be penalized 15-yards and now will be ejected. Ejections are subject to booth review and may be overturned [as with other reviews] with indisputable video evidence. If the play occurs in the first half the player is disqualified for the remainder of that game. If it occurs in the second half, the player is disqualified for the remainder of that game and the first half of the next.
There will be a 10-second run off if the only reason the clock is stopped within the last minute of a half is for an injury to an offensive player. This is similar to the rule regarding a 10-second run off for an offensive penalty in the last minute of a half.
The clock cannot be stopped by spiking the ball if less than 3 seconds remain. If one or two seconds remain the offensive can run just one more play. Down two; no time-outs; long pass completion; 2-seconds left - cannot spike the ball and bring on the field goal unit to win the game; must go for a touchdown.
If a player changes numbers during a game they must report to the referee before resuming play and the referee with make an announcement to that effect. AKA - the USC Rule.
Multiple players at the the same position cannot wear the same number. Would not have prevented what happened in Pitt v. Notre Dame this year or Pitt v. Rutgers last year.
Numbers on jerseys must be in a distinctly different solid color than the rest of the jersey.
Replay may be used to adjust the clock at the end of any quarter, not just the halves.
Officials may use electronic electronic communication devices on-field during games.
Two rules that didn't pass were the Boise State rule which would have required uniforms in contrasting color to the color of the field and one that would have switched the down and distance markers to opposite side of the field at the half.
