LUBBOCK, Texas -- Oklahoma quarterback Sam Bradford left the game against Texas Tech in the first quarter with an apparent concussion.

Before halftime of the Sooners' 34-27 loss to Texas Tech, Oklahoma coach Bob Stoops said Bradford was being monitored for a concussion.

"He's got somewhat of a concussion. They're checking him out right now," Stoops told ESPN sideline reporter Bonnie Bernstein.

Bradford came out with the Sooners up 7-3 after their second possession of the game. It appeared from television replays that he took a hard hit as he tried to make a tackle after teammate Allen Patrick fumbled on OU's first play from scrimmage. Bradford got up slowly.

Bradford sat alone on the bench until about 10 minutes remained in the first half when he walked with trainers up a ramp leading out of the stadium and stood near the top for a few minutes.

He then got on the back of a golf cart and was taken away from the stadium area.

Bradford returned to the sideline in street clothes in the second half.

Joey Halzle replaced Bradford, who came into the game as the nation's most efficient passer (180.4). Through 10 games, the redshirt freshman completed 70 percent of his passes with only six interceptions.

Halzle went 21-for-41 for 291 yards with two touchdowns and an interception in the loss.
