ANN ARBOR, Mich. — Michigan star tight end Colston Loveland will not play Saturday’s game against No. 11 USC due to an unspecified injury.

Loveland apparently suffered a shoulder injury in last weekend’s win over Arkansas State. Michigan coach Sherrone Moore did not elaborate on 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 catches.

The No. 18 Wolverines also changed their starting quarterback this week, switching from Davis Warren to Alex Orji. Warren had thrown six interceptions in three games, including three last weekend. He threw two interceptions in a 31-12 loss to Texas on Sept. 7.

Orji has only completed seven pass attempts in his career, but has rushed for 58 yards as a relief pitcher this season.

Moore said this week he wants to see Orji “take the reins” of Michigan’s offense when he gets his chance.

“I’m happy for him,” Moore said. “I know he can’t wait.”
