When No. 9 Baylor and No. 23 Texas kick off their regular season finale, they could be playing a de facto Big 12 championship game with a Fiesta Bowl trip on the line.

The winner Saturday is guaranteed at least a share of the Big 12 title. The last game ever at Baylor's Floyd Casey Stadium becomes even bigger for the Bears and Longhorns if sixth-ranked Oklahoma State loses at home against No. 18 Oklahoma earlier in the day.

Texas quarterback Case McCoy says the focus is on winning the Big 12 championship, and that means beating Baylor. Bears quarterback Bryce Petty says it doesn't matter what happens in Stillwater until after what happens in Waco.

Oklahoma State had convincing victories over both Baylor and Texas last month.
