Oklahoma quarterback Bradford cleared to play vs. Oklahoma St.

NORMAN, Okla. -- Oklahoma quarterback Sam Bradford was cleared to play Saturday against Oklahoma State.

Bradford, the nation's top-rated passer, sustained a concussion last weekend at Texas Tech, but doctors determined he's healthy enough to face the Cowboys.

"Everything has checked out and barring any unforeseen circumstances Sam will play this week," Sooners coach Bob Stoops said Thursday in a statement.

Bradford was injured in the first quarter of Oklahoma's 34-27 loss at Texas Tech, which probably knocked the 10th-ranked Sooners (9-2, 5-2 Big 12) out of national title contention. He has thrown for 2,520 yards and 28 touchdowns with only six interceptions this season.

Backup quarterback Joey Halzle completed 21 of 41 passes for 291 yards with two touchdowns and one interception in relief of Bradford against Tech.

Stoops didn't release additional information about injured defensive end Auston English, who is doubtful for Saturday. English has missed the past two games with a hairline fracture in his leg.

Oklahoma will be without leading rusher DeMarco Murray (knee), defensive end Alan Davis (concussion) and backup receiver Adron Tennell (knee).

The Sooners can clinch the Big 12 South title with a victory over rival Oklahoma State (6-5, 4-3). A win would send them into the conference championship game in San Antonio on Dec. 1.
