LOS ANGELES (AP) Southern California center Max Tuerk will miss the rest of the season with a torn knee ligament.
The Trojans (3-2, 1-2 Pac-12) announced the extent of their all-conference center's injury Sunday, several hours after coach Steve Sarkisian took an indefinite leave of absence.
Tuerk was hurt during the Trojans' 17-12 loss to Washington on Thursday. The senior made the all-Pac-12 first team last season while starting every game.
Toa Lobendahn moved over to center from left guard after Tuerk was hurt.
USC also announced that defensive lineman Claude Pelon is doubtful for Saturday's game at No. 14 Notre Dame after spraining his knee against the Huskies.
Receiver Steven Mitchell is probable with a sprained ankle, and freshman cornerback Iman Marshall is healthy after incurring an abdomen injury against Washington.
