USC's Toa Lobendahn leaves game vs. Utah with knee injury

The injuries keep piling up for interim head coach Clay Helton and his USC Trojans.

Toa Lobendahn was lost to a knee injury in the first half against Utah on Saturday and he won't return, the team announced.

Lobendahn replaced Max Tuerk at center when Tuerk went down with a season-ending knee injury against Washington on Oct. 8th.

Safety Marvell Tell also left the game with a shoulder injury and won't return.
