LOS ANGELES (AP) - Southern California running back Justin Davis has left the field on a cart with a right foot injury in the second half of the Trojans' game against No. 21 Colorado on Saturday.

Davis had rushed for 83 yards on 13 carries against the Buffaloes before exiting early in the third quarter, hobbling toward the sideline before sitting down and being attended to after a 5-yard gain.

A senior from Stockton, Davis, who attended Lincoln high school, leads USC with 467 yards rushing. He has scored two touchdowns this season.

Davis rushed for more than 120 yards in his previous two games, against Utah and Arizona State.

Ronald Jones II got more playing time in Davis' absence.
