Two first-half touchdowns by Iowa State proved enough to knock No. 4 TCU out of its seat alone at the top of the Big 12.
And maybe more.
Matthew Eaton caught a 17-yard touchdown pass in the first quarter, and Hakeem Butler caught a 4-yard scoring pass in the second quarter — enough points for the Cyclones to take a 14-7 victory at Jack Trice Stadium and hand the Horned Frogs their first loss.
TCU (7-1, 4-1), victimized by two turnovers by quarterback Kenny Hill in the red zone, lost a chance to be in the top four when the first College Football Playoff rankings are announced on Tuesday night.
