The NCAA is closing the loophole used by Oregon to shave time off the game clock at the end of Saturday's win over Ohio State, when the Ducks intentionally used 12 players on defense.

The NCAA issued a rules interpretation that will allow offenses to reset clock if 12 or more defenders participate in a play late in a half.

The Oregon Ducks’ leash on beating the rulebook has run out after coach Dan Lanning exploited a loophole regarding 12 men on the field penalties to help down Ohio State.
