CORVALLIS, Ore. (AP) - Oregon running back Kenjon Barner was injured late in the first half against Oregon State with what appeared to be a possible rib or abdomen injury.

Barner was attended to by trainers on the field after the injury, then walked gingerly to the sidelines without help. He stood on the sidelines for several minutes with his helmet on, conferring with trainers, before heading to the locker room just before halftime.

Barner rushed for 141 yards and a touchdown for the No. 5 Ducks before he was injured.

Barner was the sixth-ranked running back in the nation, averaging 129.6 yards per game, going into Saturday's Civil War rivalry game against the No. 16 Beavers.
