Michigan running back Brandon Minor undergoes rotator cuff surgery

He tried to play the following week against Wisconsin, but left in the first quarter after 7 carries and sat out the Wolverines' season-ending loss to Ohio State.

Minor's mother, Julie Gilliam, said her son is in a sling and will have his arm immobilized for the next month.

"He's still not feeling too well," Gilliam said. "They had a problem controlling his pain. He ended up having to be taken back into emergency. He was discharged (Sunday). He's doing a lot of sleeping."

One of the most physical running backs in the country, Minor led Michigan with 502 yards rushing and 8 touchdowns this year but missed 3 games with injury.

He sat out Michigan's season-opening win over Western Michigan and a mid-season game against Delaware State with a leg injury related to a preseason car accident. Gilliam said doctors told Minor that would be "a 12-week healing process" at the time.

"Of course, Brandon wasn’t going to miss his senior season and he didn’t want to redshirt," Gilliam said.

Minor, who was limited by torn ligaments in his right wrist as a junior, was on the roster for the East-West Shrine Game before surgery. He won't play in that all-star contest now, and it's unclear how his shoulder injury will affect his draft stock.

The Richmond, Va., native was projected as a late-round pick before the injury.
