Oklahoma must finish the Bedlam rivalry against Oklahoma State without its star wide receiver (and potential Heisman Trophy finalist) Dede Westbrook.

According to Fox Sports sideline reporter Bruce Feldman, Westbrook will miss the second half with an undisclosed injury.

Westbrook sustained what appeared to be a head injury in the first half against the Cowboys when he took a brutal hit on a pass over the middle. Westbrook went up for the catch and took a shoulder-to-shoulder hit from safety Jordan Sterns. However, it was the whiplash impact between Westbrook's helmet and the turf that was perhaps the most violent.

Westbrook was able to walk off the field under his own power, but was clearly suffering. Westbrook had four catches for 111 yards and a score before the injury.
