Collin Klein piled up more than 300 yards of offense before leaving in the third quarter with an undisclosed injury, and No. 3 Kansas State remained unbeaten with a 44-30 victory over Oklahoma State on Saturday night.
Klein had thrown for 245 yards and run for 64 more before sneaking in for his 50th career rushing touchdown with 9:47 left in the third quarter. The Heisman Trophy frontrunner didn't return to the field on the Wildcats' next offensive series.
By that point, the Wildcats (9-0, 6-0 Big 12) simply had to protect a 38-17 lead.
Oklahoma State's Wes Lunt also left with an injury after throwing his third interception in the third quarter. The freshman quarterback, who missed six weeks with a knee injury earlier this year, threw for 184 yards and a touchdown before giving way to Clint Chelf.
Chelf, a junior, almost brought the Cowboys all the way back. He ended the game 16 of 27 for 233 yards, a touchdown, and an interception.
It's not known if Chelf will be the starter when OSU hosts West Virginia on November 10th.
