EUGENE, Ore. -- Oregon running back Royce Freeman and quarterback Justin Herbert both left against California on Saturday night.
Freeman headed for the locker room accompanied by a trainer with more than eight minutes to go in the first quarter. The exact nature of the injury was unclear, but it appeared to be a shoulder.
Herbert left at the end of the first quarter after a 7-yard touchdown run. He had thrown a touchdown pass as Oregon built a 17-0 lead against the Golden Bears.
Both players were listed as questionable for a return to the game.
Freeman had already run for 51 yards when he was injured.
The senior has rushed for 541 yards and an NCAA-leading 10 rushing touchdowns this season. Freeman ranks ninth nationally with an average of 135.25 yards a game.
Oregon was already missing senior receiver Charles Nelson because of a right ankle sprain.
