TCU overcame five turnovers to upset No. 19 Oklahoma State, 29-22, on Saturday, dealing a significant setback to the Cowboys' hopes of playing for the Big 12 title.
In the meantime, Iowa State clinched its first-ever trip to the Big 12 championship game before it even kicked off against West Virginia, thanks to Texas's 69–31 victory against Kansas State.
The Horned Frogs got off to a rocky start on Saturday, falling behind 13–0 in the first quarter thanks partly to a missed field goal and a fumble that the Cowboys returned for a touchdown.
TCU quarterback Max Duggan helped his team power back, tallying 12-of-26 passing for 265 yards with one touchdown and one interception as well as 104 yards rushing with two touchdowns on 19 carries.
