No. 2 Ohio State was losing by a touchdown on the road to No. 8 Wisconsin in the second quarter. A referee close to OSU’s sideline signaled for the clock to start running after a play was called dead. Buckeye head coach Urban Meyer accidentally walked into the ref as he was giving a signal.

Meyer was then hit with a 15-yard penalty for physical interference. “Physical interference with an official is a foul charged to the team for unsportsmanlike conduct,” per the NCAA rulebook.

Technically, no one on the sideline is supposed to stand in the white box during a play, even though coaches get away with it all the time. Stepping in the white box usually just gets you a warning, if anything, unless you actually get in an official’s way.

But a flag gets thrown when you make physical contact with a referee, which is an automatic 15-yard penalty. In this case, that was Meyer getting smacked in the face.
