NORMAN, Okla. — DeMarco Murray ran for two touchdowns, Ryan Broyles returned a punt 88 yards for a score and Oklahoma knocked No. 11 Oklahoma State out of contention for its first appearance in the Bowl Championship Series with a 27-0 win Saturday.

With representatives of the Fiesta and Orange bowls watching on, the Cowboys (9-3, 6-2 Big 12) fell completely flat with their worst offensive performance of the decade.
Oklahoma State was shut out for the first time since 2005 by an Oklahoma (7-5, 5-3) defense coming off its worst outing of the year in a loss at Texas Tech last week.
Zac Robinson threw for only 44 yards on 9-for-21 passing after missing last week’s game with injuries to his head and shoulder. He was pulled in the fourth quarter with his lowest passing total since taking over as the starting quarterback early in the 2007 season.
