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.

A rules loophole that allowed Oregon to gain an advantage by using 12 players on a key play late in its win over Ohio State last week is closed. On Wednesday, NCAA coordinator of officials Steve Shaw announced a new interpretation of the rule that will keep teams from replicating what the Ducks did in the closing moments of their 32-31 win over the Buckeyes.

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 NCAA football rules committee has issued guidance to close a loophole that allowed second-ranked Oregon to exploit an illegal substitution penalty late in its victory over Ohio State to take time off the clock.

Rulebook thumpers watched in awe Saturday night as Dan Lanning found a new and innovative way to manipulate the game clock in Oregon's win against Ohio State. It caused the NCAA to change its rules within days.
