Stoops: No update on Bradford

Oklahoma quarterback Sam Bradford had an MRI and an X-ray that revealed "no new injury," only an "aggravation" of the previous shoulder sprain, a source told ESPN's Joe Schad on Sunday night.

That source also said a course of action for treatment will be determined in the "coming days."

Sooners coach Bob Stoops said earlier Sunday that he had no update on Bradford's condition.

Bradford sustained an injury to his right shoulder on the first play of the Sooners' second possession in their 16-13 loss to Texas when he was sacked by Texas cornerback Aaron Williams. Bradford sustained a third-degree sprain to the same shoulder that caused him to miss three games earlier in the season after he was injured in Oklahoma's season-opening loss to BYU on Sept. 5.

Stoops said it is unlikely there will be any announcement about Bradford's injury before Thursday.

The 3-3 Sooners (No. 25 AP) travel to Kansas (No. 25 BCS, No. 24 AP) on Saturday.
