Kansas State quarterback Collin Klein left Saturday's 44-30 win against Oklahoma State in the third quarter with an undisclosed injury.

He appeared to suffer an injury on a 1-yard touchdown that he ran in to give the team a 38-17 lead with under 10 minutes to play in the third. It was the 50th rushing touchdown of his career.

The score put Kansas State up 38-17 and redshirt freshman Daniel Sams came on to take Klein's place under center in the Wildcats' next offensive series.
