Oklahoma's national championship chances may be out the window because of an injury to quarterback Sam Bradford.
Bradford was apparently injured on OU's first play from scrimmage. On the play, OU running back Allen Patrick fumbled the handoff from Bradford and the ball was picked up by Texas Tech linebacker Marlon Williams. As Williams was dashing downfield, Bradford tackled him.
However, nothing seemed out of sorts, because Bradford came back in for the ensuing OU series, which ended with a punt after five plays. But when Bradford came off the field, a pair of OU trainers rushed to his aid.
On the next series, OU backup quarterback Joey Halzle replaced Bradford.
