Ohio State injury update

Posted by ESPN.com's Adam Rittenberg

Ohio State starting defensive end Lawrence Wilson will miss Saturday's game at No. 20 Michigan State (ABC, 3:30 p.m. ET) after sustaining a knee injury against Purdue. Wilson, who has 18 tackles and a sack this season, anchors a Buckeyes defensive line that will face a major test in Michigan State running back Javon Ringer. Junior Rob Rose likely will start in his place.

Buckeyes head coach Jim Tressel said reserve wide receiver Dane Sanzenbacher (concussion), tight end Rory Nicol and linebacker Austin Spitler will return Saturday. Tressel won't know the status of reserve running back Dan "Boom" Herron until after Wednesday's practice. Herron sustained a concussion Oct. 4 at Wisconsin and missed the Purdue game.

"His was a little bit more significant of a concussion than Dane," Tressel said.
