NORMAN — Oklahoma quarterback Sam Bradford will play Saturday against Oklahoma State. “Everything has checked out and barring any unforeseen circumstances Sam will play this week,” coach Bob Stoops said Thursday. Bradford suffered a concussion last weekend at Texas Tech. But coaches said he had progressed well during practice this week and doctors cleared him Thursday. Bradford leads the nation in passing efficiency and needs just two touchdown passes to break the national freshman record for TD throws in a season. Stoops didn’t release any more information about injured defensive end Auston English, who is doubtful for Saturday. Since having a rod inserted into his right ankle last week to stabilize a hairline fracture, English has only been able to participate in light drills. The Sooners already will be without leading rusher DeMarco Murray due to a dislocated kneecap, as well as defensive end Alan Davis (concussion) and wide receiver Adron Tennell (knee).
