ANN ARBOR, Mich. -- Michigan star tight end Colston Loveland has been ruled out of Saturday's game against No. 11 USC with an undisclosed injury.
Loveland suffered an apparent shoulder injury in last weekend's win over Arkansas State. Michigan coach Sherrone Moore hasn't specified the nature of the injury.
Loveland, a preseason All-American, leads the Wolverines with 19 catches for 187 yards; no other Michigan pass-catcher has more than nine receptions.
The No. 18 Wolverines also changed starting quarterbacks this week, moving from Davis Warren to Alex Orji.
