DALLAS (Interstat) — In a stunning reversal of pregame expectations and a dominant defensive display, the Texas Longhorns dismantled the previously unbeaten and favored Oklahoma Sooners 23-6 on Saturday at a raucous Cotton Bowl.

A crowd of 92,100 witnessed a Texas defense that harassed Oklahoma quarterback John Mateer all afternoon, intercepting him three times and sacking him five times, while the Longhorns’ offense, led by a methodical Arch Manning and a relentless ground game, controlled the clock and steadily pulled away.

The victory, a significant rebound from a loss at Florida the previous week, improved Texas to 3-2 on the season, while handing Oklahoma its first loss, dropping the Sooners to 5-1. The final score defied the pregame narrative, as Interstat’s game simulator had projected a narrow 28-27 Oklahoma victory, and oddsmakers had installed the Sooners as 1.5-point favorites.

The game began as a defensive struggle. Oklahoma struck first on its opening drive, moving the ball efficiently. Mateer connected with Isaiah Sategna III for a 23-yard gain and later hit Deion Burks for 18 yards to push into Texas territory. But the drive stalled inside the 25-yard line, forcing the Sooners to settle for a 42-yard Tate Sandell field goal.

Texas’s offense sputtered in response, with a promising drive ending when Mason Shipley missed a 55-yard field goal attempt late in the first quarter. Oklahoma extended its lead early in the second quarter with another Sandell field goal, this time from 41 yards, to go ahead 6-0.

The momentum of the game, however, began to shift decisively in the second quarter. Texas finally got on the board with a 22-yard Shipley field goal, capping a 16-play, 76-yard drive that consumed over five minutes. The key play was a 37-yard burst up the middle by running back Quintrevion Wisner, who finished the day with 94 yards on 22 carries.

Just before halftime, Oklahoma was driving to potentially extend its lead, moving into Texas territory in the final minute. But on first down from the Texas 30, Mateer’s pass was intercepted by Texas defensive back Malik Muhammad in the end zone for a touchback, preserving the 6-3 score at the break.

The second half belonged entirely to the Longhorns. They received the opening kickoff and embarked on a masterful 15-play, 89-yard touchdown drive that took over seven minutes off the clock. Manning, who finished an efficient 21 of 27 for 166 yards, capped the drive with a 12-yard touchdown pass to DeAndre Moore Jr., giving Texas its first lead at 10-6.

The Texas defense continued its suffocating pressure, forcing a quick Oklahoma punt. The Longhorns then added a 48-yard Shipley field goal on their next possession to extend the lead to 13-6 heading into the fourth quarter.

Any hope of an Oklahoma comeback was extinguished early in the final period. On the first play of the quarter, Mateer was intercepted for the third time, this time by Graceson Littleton, who returned it 11 yards to the Oklahoma 44. Though Texas missed a subsequent field goal, the ensuing possession for Oklahoma proved disastrous.

After a series of penalties and negative plays pushed the Sooners back to their own 17, Grayson Miller’s punt was fielded by Ryan Niblett at the Texas 25. Niblett then electrified the Texas faithful, weaving his way through the coverage for a 75-yard punt return touchdown, breaking the game open and putting the Longhorns ahead 20-6 with under 10 minutes to play.

Oklahoma’s offense, which had been held in check throughout, could not muster a response. The Texas pass rush, led by Colin Simmons and his 2.5 sacks, continued to overwhelm the Sooners’ offensive line. Mateer was sacked on consecutive plays on one fourth-quarter drive, effectively ending any threat. He finished the day 20 of 38 for 202 yards with three interceptions and was held to just 5 net rushing yards.

Texas put the final exclamation point on the victory with a clock-draining drive in the final minutes, culminating in Shipley’s third field goal of the day, a 39-yarder with 2:59 remaining to set the final score at 23-6.

The Texas defense was the undeniable star of the game. Beyond the three interceptions and five sacks, they held Oklahoma’s offense, which had been averaging over 30 points per game, to just two field goals. Michael Taaffe led all tacklers with nine, including a sack, while Jelani McDonald added eight and Anthony Hill Jr. had seven. Simmons’ disruptive presence was felt consistently in the Oklahoma backfield.

For Texas, the win provides massive momentum as they head into a road game at Kentucky next Saturday. Oklahoma, meanwhile, must regroup from its first defeat as it travels to face South Carolina, its perfect season and national championship aspirations now facing a stern test after a humbling day in Dallas. The total points scored, 29, fell far under the betting over/under line of 44.5, a testament to the defensive struggle that defined the contest.
