More bizarre play occurred on several “onside-kickoffs” near the end of the game. Entertaining.
On the disputed punt runback, Memphis had two players with the #4 on the field at the same time - a penalty. That was pointed out by the television announcers. That’s why some players “change jerseys” during the game, to prevent being penalized for having two players with the same number on the same team out on the field at the same time.
