Bradford unlikely to return in second half

Posted by ESPN.com's Tim Griffin

DALLAS -- Oklahoma quarterback Sam Bradford likely won't return for the rest of the game.

Bradford attempted to throw for several minutes along the side. His throws lacked zip and he did not attempt to throw a pass of longer than 15 yards.

His replacement Landry Jones has played well, completing 12 of 23 passes for 130 yards. Jones directed the Sooners' second-scoring drive on his second possession which is the difference in the Sooners' 6-3 lead over Texas.

Update: Sam Bradford is out of his pads and is pacing the Sooners' sideline.
