And the play originally resulted in a stopped clock and the new call (after replay) would’ve resulted in a running clock then there is a 10 second runoff (or the offense can choose to use a TO to avoid it). A game ended that way a few years back. Think it was Kentucky who was originally ruled to have scored a TD with less than 10 seconds on the clock, but replay called him short, Kentucky did t have a TO and the game was over.
