Senior tailback Damien Williams is no longer with Oklahoma's football team.
Coach Bob Stoops announced Williams' dismissal on Monday. Williams, from San Diego, had been suspended for Saturday's win at Kansas State and earlier served a one-game suspension against Tulsa.
Williams started one game this season and was the 20th-ranked Sooners' second-leading rusher, with 114 carries for 553 yards and seven touchdowns. He also had caught nine passes for 90 yards.
Last season, Williams rushed for 946 yards and 11 touchdowns and caught 34 passes for 320 yards and another score while starting nine games for Oklahoma.
Wide receiver Lacolton Bester, who also was suspended for the Kansas State game, will be available to play against No. 7 Oklahoma State on Dec. 7.
