In 2006, the
NCAA Football Rules Committee enacted instant replay guidelines and added them to the football playing rules. For games involving two schools from the same conference, league policy determines whether replay will be used. For non-conference games, the home team makes the determination.
Plays involving the sideline, goal line, end zone and end line, as well as other detectable situations, are reviewable (e.g., fumble/no fumble, pass complete/incomplete, touchdown/no touchdown, runner down/not down, player or ball inbounds/out of bounds, clock adjustments).
Most fouls (e.g., holding, offside, pass interference) are not reviewable, except that in 2006, illegal forward passes, handoffs and punts from beyond the line of scrimmage, and too many players on the field are reviewable and the foul may be called after replay review. Also, while the foul of pass interference is not reviewable, it can be overturned on review based on touching of the pass. By rule, pass interference cannot apply if a pass has been touched by any player before the foul occurs, and the touching of a pass is a reviewable play at its conclusion from a secure booth in the press box. Most plays are routine and the game continues without interruption. If, however, the following criteria are met, the Replay Official may interrupt the contest by paging the game officials to stop the game before the next play starts. The criteria are:
- There is reasonable evidence to believe an error was made in the initial on-field ruling.
- The play is reviewable.
- Any reversal of the on-field ruling, which can only result from indisputable video evidence, would have a direct, competitive impact on the game.
Once per game, each head coach may also call a timeout and challenge the ruling on the previous play before the next play starts. A coach must have at least one timeout remaining in order to challenge (teams receive three timeouts per half). If the challenge is successful and the on-field ruling is overturned, the team keeps its timeout and is allowed only one more challenge. If unsuccessful, the team loses its timeout and is allowed no more challenges.
After reviewing the play from available video angles, the Replay Official decides if the call should be upheld or overturned. If the call is overturned, the Replay Official provides the proper information to restart the play, such as the team in possession, the yard line where the ball should be placed, the correct down and distance, and the correct time on the stadium clock. Should there have been an official score change, the score will be changed again, resulting in the original score.
