One-minute warning


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 last half-minute of regulation or overtime.
At the half-minute mark of regulation or overtime, the referee announced: "One-minute Timing Rule in effect". During the final minute of play, the game clock changes from a continuously running clock to a clock that mostly mirrored NCAA rules For most of the league's history, any play that did not advance the ball across the line of scrimmage also stopped the clock; this prevented teams from kneeling to run out the clock. It also rewards defensive play, as a tackle for loss automatically stops the clock. Any player injured during this time and that team uses a timeout. The original one-minute timing rules are still in effect in the China Arena Football League.
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.
