NORMAN, Okla. — Heisman Trophy winner Sam Bradford will not start for No. 8 Oklahoma on Saturday at No. 17 Miami.

Sooners coach Bob Stoops said Thursday that Landry Jones will start for Bradford, who hasn't played since spraining the AC joint in his right, throwing shoulder the first week of the season.

"Sam has made daily progress, but we don't feel like he's quite where he needs to be yet," Stoops said in a statement. "Our team has a lot of confidence in Landry's ability and we're looking forward to going into the game with him at quarterback. Our approach will be the same that it has been in the last two games."

Stoops did not say whether Bradford could serve as Jones' backup.

Bradford sprained his shoulder when he was slammed to the turf while being sacked late in the first half of Oklahoma's 14-13 loss to BYU on Sept. 5.

Jones, a redshirt freshman, replaced Bradford in the next two games, which were back-to-back shutouts against Idaho State and Tulsa.

Jones, threw a school-record six touchdown passes in a 45-0 victory over Tulsa on Sept. 19, OU's last game.

For the season, Jones is 49 for 81 for 673 yards with nine touchdowns and three interceptions.
