Oregon defensive tackle A’Mauri Washington exits game against Oklahoma State

Oregon defensive tackle A’Mauri Washington left the field with trainers during the second quarter of Saturday's game against Oklahoma State. The senior defender, who started all 15 games last season, walked to the locker room under his own power after contributing to the defensive front. Oregon currently trails Oklahoma State 24-17 at halftime at Boone Pickens Stadium. The matchup was previously delayed due to thunderstorms and lightning in the area. Washington had recorded one notable play in the first half by stopping a third-and-1 run, though he also committed an offsides penalty. No diagnosis or potential return status has been announced for the Oregon starter as the game continues.
