Unlike the NFL, every play in college football is reviewed by the Replay Official in the press box. If the Replay Official believes the previous play was ruled in error and the play had a direct, competitive impact on the game, he may stop play for review by paging the officials on the field.

The only other way a play can be reviewed is if the head coach challenges the previous play. However, each team is limited to only one challenge per game, regardless of the outcome of any previous challenge. If a coach challenges a play, and the play is not reversed, the challenging team will lose a timeout.
