Key stat: K-State held the ball for nearly 10 minutes in the quarter.

Fourth quarter

Key play: With Oklahoma State driving for a score with about two minutes left, Chapman intercepted his third pass of the night, maintaining K-State’s 44-30 lead.

Key stat: K-State quarterback Collin Klein spent the entire quarter on the sideline.

Reason to hope: K-State is undefeated after nine games.

Reason to mope: It’s always nerve-racking when a starting quarterback leaves the game for any reason.

Looking ahead: K-State heads next Saturday to TCU, which defeated West Virginia in overtime on Saturday. The Horned Frogs have been up and down this season, but have a strong defense and showed poise beating the Mountaineers.
