COLUMBUS, Ohio - Ohio State says coach Urban Meyer will retire after Rose Bowl.
After seven years and a national championship at Ohio State, the 54-year-old Meyer will formally announce his departure Tuesday at a news conference.
The university didn't say why he was retiring, but Meyer has said he suffers from debilitating headaches caused by an arachnoid cyst in his brain.
He was also battered this year by an offseason issue involving a now-fired assistant coach that led to Meyer's suspension for the first three games of the season.
The university says offensive coordinator Ryan Day, who served as interim coach during for the first three games of this season, will be named the new head coach.
