An Ohio lawmaker has introduced legislation that would make it a felony offense for an opponent to plant its flag in the center of Ohio Stadium.The O.H.I.O. Sportsmanship Act introduced Tuesday by Republican state Rep. Josh Williams comes in response to a midfield brawl that broke out in Columbus on Nov. 30 after Michigan upset Ohio State 13-10.Wolverines players attempted to plant their flag on the Buckeyes’ logo after the game, sparking fights among members of both teams as stadium security, police and coaches attempted to intervene and restore order.Officers used pepper spray to help quell the incident, which drew $100,000 fines for both schools from the Big Ten.Williams’ bill would “prohibit planting a flagpole and flag in the center of the Ohio Stadium football field on the day of a college football game.”
