COLUMBUS, Ohio -- Ohio State coach Ryan Day had his left hand on his hip and his right arm around cornerback Jermaine Mathews Jr.
As the Ohio State band played "Carmen Ohio" following another loss to rival Michigan on Nov. 30, and the team gathered -- as it does after every home game -- to sing along, Day glanced up at the scoreboard. Boos rained down from the Ohio Stadium crowd, drowning out the alma mater.
Suddenly, Mathews turned and sprinted toward midfield, where the Wolverines had planted their flag. Day turned to see what was happening but, as if frozen in shock, only took a few steps and watched as players from both schools clashed -- a melee that lasted five minutes and left a university police officer hospitalized.
