Landry Jones and Oklahoma treated their regular-season finale like a championship game - and finished wearing caps and T-shirts declaring the 12th-ranked Sooners the Big 12 champions.
They then had to wait to see if they would have to share their eighth Big 12 title, or win it outright.
"Technically, we're not sharing anything with anybody right now," Sooners defensive end R.J. Washington said. "Right now, we're the only Big 12 champions. We'll see what happens later. Sharing it or not sharing it, winning the conference championship is great."
With their 24-17 victory Saturday, after TCU's fourth-down pass to the goal line in the final minute was knocked down incomplete, the Sooners (10-2, 8-1 Big 12) clinched at least a share of their Big 12 title - and likely a BCS berth no matter what happens.
"In the end, it's just great to be in this position and to be a winner again," coach Bob Stoops said. "For these guys, Big 12 champs, or co-champs, they're recognized as champions."
Jones threw for 244 yards and two touchdowns as the Sooners won their eighth consecutive Big 12 game since a late-September loss to Kansas State.
The Wildcats played their regular-season finale at home Saturday night against No. 23 Texas. Oklahoma would have the outright title and guaranteed BCS spot if the seventh-ranked Wildcats lose.
The Sooners, whose only other loss was to No. 1 Notre Dame, are in good shape for the final at-large BCS berth if K-State wins. Kent State's double-overtime loss to Northern Illinois in the MAC championship game likely ended any chance for that league to get in the Bowl Championship Series.
