AT&T Stadium in Arlington, Texas, is the site for "College GameDay" and the Big 12 championship as the No. 4 TCU Horned Frogs take on the No. 10 Kansas State Wildcats.

The Horned Frogs enter the Big 12 title game as one of three undefeated teams in the FBS and could solidify their spot in the College Football Playoff with a victory. It would be the first time TCU has reached the CFP, which started in 2014.
