DALLAS — Like a throwback to Red River games from yesteryear, the Oklahoma defense played a leading role in a victory over Texas.

The No. 6 Sooners sacked Longhorns quarterback Sam Ehlinger nine times in a 34-27 win Saturday at the Cotton Bowl.

CeeDee Lamb (10 catches for 171 yards and three touchdowns) was the star for an OU offense that missed golden opportunities in the first half. The Sooners twice turned the ball over inside the Texas 20-yard line (one Jalen Hurts fumble, one Hurts interception), keeping the Longhorns deficit just seven until late in the second quarter.

But the OU defense played with an aggression missing in recent years, led by linebacker Kenneth Murray's five tackles and a sack. Delarrin Turner-Yell was the Sooners' leading tackler with 10.

No. 11 Texas tied the game at 10 midway through the third quarter, but OU immediately answered with a three-play, 75-yard drive that ended with a 51-yard touchdown pass to Lamb on a flea-flicker.

Hurts hit Lamb for a 27-yard score early in the fourth quarter after Texas had cut the margin to 20-17.

Hurts overcame his early mistakes to finish with more than 300 yards of offense. His 3-yard rushing touchdown with less than five minutes increased the lead to 34-20.
