Heisman Trophy winner Sam Bradford is not expected to need surgery on his sprained right shoulder and the quarterback could play again for No. 3 Oklahoma in two to four weeks.

"Everyone's different in how they heal, the soreness, how they handle it and how quickly it dissipates where he can move and be comfortable again throwing the ball," coach Bob Stoops said after the Sooners' practice yesterday. "Anywhere from two to four weeks is what we're anticipating."

Stoops said the initial evaluations by doctors showed that Bradford did not suffer any damage to his collarbone, rotator cuff or other parts of his shoulder when he sprained his AC joint just before halftime in Oklahoma's 14-13 loss to No. 20 BYU on Saturday. Those evaluations also did not suggest surgery, although another doctor's opinion is due in today.

"After that opinion does come in, I probably will have to sit down with the coaches and my family one more time just to make sure that getting back out there is the right decision for me," Bradford said.

Bradford was considered a potential No. 1 overall pick in this year's NFL draft before he decided instead to return for his junior year at Oklahoma, with his primary goal to win the national championship he narrowly missed a year earlier.

The Sooners lost to Florida, 24-14, in the title game.
