Stoops did not give a timetable for the possible return of Bradford, who re-injured his right shoulder Saturday in a 16-13 loss to Texas. Landry Jones replaced Bradford against the Longhorns and will start against Kansas.
Bradford, winner of last season's Heisman Trophy, injured his shoulder when he was hit by Aaron Williams in the first period. Bradford originally injured the shoulder in a season opening loss to Brigham Young and did not return until Oct. 10 against Baylor.
Jones started games against Idaho State, Tulsa and Miami. He threw a school record six touchdown passes against Tulsa.
