Ohio State says quarterback Braxton Miller will miss the 2014 season after reinjuring his throwing shoulder.
Miller, a two-time Big Ten player of the year, left practice in pain Monday after making a throw.
Ohio State said Tuesday Miller will require surgery.
It's a huge blow to the nation's No. 5 team, which already has several major holes to fill on offense.
The senior and three-year starter partially tore the labrum in his right shoulder in a loss to Clemson at the Orange Bowl. He had surgery, did not face contact in spring practice and was held out of several practices this month due to soreness.
Redshirt freshman J.T. Barrett is Miller's top backup and will likely be the starter in the Aug. 30 opener against Navy in Baltimore.
