Paul Dawson returned an interception 41 yards for a touchdown, TCU made a huge fourth-and-1 stop with just over 3 minutes left and the No. 25 Horned Frogs remained undefeated with a 37-33 victory over No. 4 Oklahoma on Saturday.

Oklahoma (4-1, 1-1 Big 12) had the ball after the two teams had three turnovers in a span of four plays — another interception by Trevor Knight between two fumbles by TCU.

On fourth down from the TCU 22, Samaje Perine was stuffed by linebacker Marcus Mallett for no gain. Officials confirmed on a replay review that Perine, who had three TD runs in the game, was stopped short of a first down.

Dawson's big pick for TCU (4-0, 1-0 Big 12) came with 14:12 left. He reached up with both hands to grab the ball and raced untouched for a score to make it 37-31.
