*Bradford leads Oklahoma to Big 12 title game*

NORMAN, Oklahoma (Ticker) -- Sam Bradford was not going to let a concussion keep him down.

Bradford tossed four touchdown passes as the 10th-ranked Sooners routed Oklahoma State, 49-17, in the "Bedlam Series" on Saturday to clinch a berth in the Big 12 Conference championship game.

Knocked out of the national championship picture with last week's 34-27 loss to Texas Tech, the Sooners rebounded to win the Big 12 South Division title.

Oklahoma will face the winner of Saturday night's showdown between Kansas and Missouri in the Big 12 title game next week in San Antonio.

The Sooners (10-2, 6-2 Big 12 South) played Saturday's contest without leading rusher DeMarco Murray, who was sidelined with a dislocated kneecap suffered last week.

But Bradford, the national leader in passing efficiency, was cleared on Wednesday after being forced out last week with a concussion and responded by setting an NCAA record for touchdown passes by a freshman.

The four TDs give Bradford 32, breaking the previous freshman mark of 30 set by Nevada's David Neill in 1998 and matched by Texas' Colt McCoy last season.

Oklahoma grabbed control early, scoring a pair of touchdowns in the first nine minutes to open a 14-0 lead.

The Sooners stretched their lead to 28-7 on Bradford's two-yard TD pass to Joe Jon Finley with 2:25 left in the first half.

The Cowboys tried to rally in the second half, closing to 28-17 on Dantrell Savage's six-yard TD run with 4:24 left in the third quarter.

But Oklahoma reeled off 21 unanswered points to turn the contest into a rout.

Despite the four touchdowns, Bradford finished just 11-of-15 for 150 yards.
