Penalty
15 yards from the succeeding spot. Automatic first down for Team B fouls if not in conflict with other rules. Disqualification for the remainder of the game and the first half of the next game [S7, S27 or S38, and S47]. For fighting in the last game of a season, those with remaining eligibility shall serve suspensions during the first game of the next season for which they are eligible.
Not sure if anything would change since it wasn't during the game and there were no disqualifications.
