As if Michigan didn't have enough going against it this weekend, head coach Rich Rodriguez said today that starting right tackle Stephen Schilling sprained his knee at Tuesday's practice and is questionable for the Ohio State game (ABC, noon ET).
Schilling was Michigan's only returning starter on the offensive line and one of the few linemen to survive the season without injury. Perry Dorrestein would start in Schilling's place if he misses the game.
Rodriguez also announced that defensive tackle Jason Kates has left the team. Kates didn't play much this season, but he's the second player to leave the program this week. Wide receiver Zion Babb was dismissed for violating team rules.
Rodriguez admits that other players could soon be leaving the program as well.
"That's it right now, but there may be more attrition," he said. "We've asked the guys, and we've been pretty honest with them all along ... we want everybody to make a total commitment to our football program, especially academically. If they're not upholding what they do academically and athletically, then really they need to see if this is the spot for them.
"It's not easy, but a lot of our guys have made a tremendous commitment. A handful, maybe, haven't. We'll see what happens in the next few weeks."
Freshman running back Sam McGuffie attended a family funeral today. He will rejoin the team later this week and could play Saturday. After practicing last week, McGuffie didn't play against Northwestern, telling running backs coach Fred Jackson he was "too banged up" to play.
