Oklahoma will be without its starting left guard against South Dakota.
Sophomore Marquis Hayes isn't dressed out for the 6 p.m. contest. The Maryland Heights, Missouri native started last weekend at left guard.
Virginia graduate transfer R.J. Proctor is expected to start in Hayes' place.
Oklahoma defensive lineman Dillon Faamatau is suited up. Faamatau missed the Houston game due to an undisclosed injury.
