The Ohio State-Michigan flag-planting brawl was just one of several incidents that started scuffles in college football during Rivalry Week.

Moments after Michigan shocked No. 2 Ohio State 13-10 for their fourth straight rivalry victory, players from both teams broke out in fisticuffs at midfield. Wolverines defensive tackle Mason Graham was being interviewed by the broadcast when a fracas broke out behind him.

Michigan edge rusher Derrick Moore was in the middle of melee, holding his team’s flag and trying to plant it on the Buckeyes’ famed logo. And Ohio State linebacker Jack Sawyer, who had an interception in the game, ripped the Michigan flag away from the Wolverine players before tensions finally calmed down.
