Redd suffered the injury when the Trojans were up 21-0, well on their way to the routing Cal 62-28 in Berkeley. Redd carried the ball six times for 19 yards in the game, adding a 12-yard touchdown reception thanks to a shovel pass from Cody Kessler.
This is just the latest in a series of injury woes for the senior running back, who suffered a left knee injury in spring practice that kept him out of USC's first five games. Since returning to action, Redd has recording 76 carries for 351 yards and one touchdown.
With running Tre Madden also out because of a hamstring injury, the Trojans called on redshirt sophomore Javorius Allen. Allen ran for 133 yards and three touchdowns last week against Oregon State, and kept thing rolling with 134 yards rushing and three total toucdhowns (two rushing, one receiving) against the Bears. USC's passing attack has stalled at times this season, but the ground game has been consistent most of the season thanks to a stable of talented backs.
