The Big 12 championship game matchup is set after No. 12 Iowa State and No. 13 Oklahoma won their games Saturday.
Iowa State (8-2, 8-1 Big 12) clinched a spot in its first title game and the best conference record in the regular season with a 42-6 win over West Virginia at home. The five-time defending Big 12 champion Sooners (7-2, 6-2) later beat Baylor 27-7.
The title game is Dec. 19 at AT&T Stadium in Arlington, Texas.
Oklahoma has a six-game winning streak since a 37-30 loss at Iowa State on Oct. 3, when the Sooners were 0-2 in Big 12 play for the first time since 1998.
Iowa State opened this season with a 31-14 home loss to Louisiana-Lafayette, but its only Big 12 loss was 24-21 at Oklahoma State on Oct. 24. The Cyclones last won a conference title in 1912 when they shared a Missouri Valley Conference crown with Nebraska.
The Cyclones have completed their regular season. Oklahoma plays at West Virginia next Saturday to make up a game postponed from Nov. 28, but holds tiebreakers over both No. 19 Oklahoma State and Texas.
Oklahoma is 10-1 in Big 12 championships games, including all three since the game was reinstated after a six-year hiatus. It will be the Sooners' 12th appearance in the last 15 Big 12 title games, a streak that started with their 2000 national championship.
