Texas starting defensive back Ryan Watts is doubtful to play in Saturday's game against Oklahoma, sources told ESPN's Pete Thamel.
Watts hasn't practiced this week after suffering a lower-body injury against Kansas.
Freshman Malik Muhammad and Wake Forest transfer Gavin Holmes are expected to get more snaps for Texas in Watts' place as the Longhorns look to stop quarterback Dillon Gabriel, who has 1,593 passing yards and 15 passing touchdowns this season.
Longhorns tight end Ja'Tavion Sanders is set to play after also suffering an injury against the Jayhawks, coach Steve Sarkisian said earlier this week.
