Oklahoma defensive tackle Casey Walker was taken to the hospital by ambulance Wednesday after suffering a throat injury during practice.
The injury, however, was not serious, and Walker was treated and released.
Walker, a junior, has started seven games this season. He has not been ruled out for the Sooners game against Iowa State on Saturday.
