Michigan will be without Colston Loveland in Saturday’s home matchup against No. 11 Southern California, as the team’s star tight end was ruled out of the game with an undisclosed injury.In last weekend’s 28-18 win over Arkansas State, Loveland appeared to suffer a shoulder injury, though Wolverines coach Sherrone Moore hasn’t revealed specifics about the injury.Loveland’s 19 receptions this season not only leads the team, but no other pass catcher for No. 18 Michigan has more than nine total catches.
