The ruling from NCAA Football Secretary-Rules Editor Steve Shaw comes just days after Oregon coach Dan Lanning told the media he purposely took a 12-men on the field penalty to help run out the clock and close out the Buckeyes, 32-31.

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.

The Ducks and other teams won’t be able to burn precious seconds off the clock anymore by putting 12 men on the field for plays in the final two minutes of a half.
