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.

Oregon’s apparent ingenuity has led to an in-season rule change. The NCAA sent out a rules memo Wednesday outlining the new procedures for officials when a team commits a substitution foul inside the final two minutes of either half.

No. 2 Oregon had 12 men on the field late in its 32-31 win over No. 4 Ohio State, with the resulting penalty causing precious seconds to wind off the clock.
