Sooners' Marquise Brown suffers apparent ankle injury

Oklahoma Sooners wide receiver Marquise Brown was carted from the sideline to the Sooners' locker room after suffering what appeared to be an ankle injury during the Big 12 Championship game Saturday.

Brown, an All-Big 12 selection and the Sooners' leading receiver, had been battling an ankle sprain for much of the season. He had five catches for 54 yards against the Texas Longhorns before taking a big hit after the fifth one.

Brown limped to the bench and stayed there until the cart picked him up.

Brown had 70 receptions, 1,264 receiving yards and 10 touchdowns entering Saturday's game.
