Patrick Lavine's 20-yard interception return for a touchdown has boosted Oklahoma State to a lead over Texas Tech and put the Cowboys close to putting this one away.
The apparent Oklahoma State victory could put Texas' South Division title hopes on ice at least for a week.
The Longhorns could have clinched an appearance in the Dec. 5 Big 12 title game with an Oklahoma State loss.
That will have to wait until next week, when the Longhorns host Kansas.
But the Red Raiders will be going against a tired Tech defense without linebacker Marlon Williams, who was just carted off the field for the locker room with a leg injury.
