The one-minute warning or the one-minute timing rule was a rule that dictated the flow of the game in the final minute of a half in some indoor American football leagues, most prominently the Arena Football League. During the AFL's final season in 2019, it occurred in the last half-minute of regulation or overtime. In the former X-League, after the one-minute warning or in overtime, the "X-Bonus" rule came into play. All scoring during the final minute of play was worth double what it is normally worth, and a special black football was used.
