MANHATTAN, Kan. (AP) — Third-ranked Kansas State's perfect season remained intact Saturday night.
So did its national title hopes.
The future of both may be in jeopardy, though, after Heisman Trophy front-runner Collin Klein left in the third quarter of a 44-30 victory very Oklahoma State with an undisclosed injury.
Kansas State coach Bill Snyder declined to discuss the nature or severity of it afterward, and said he wasn't sure whether Klein would be available for next Saturday's game at TCU.
"Obviously he was injured or we wouldn't have taken him out," Snyder said.
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 to give Kansas State a 38-17 lead.
It wasn't clear when he got hurt, but Daniel Sams played the rest of the way.
"Without Collin at quarterback, we had to do some adjustments," said Tyler Lockett, who had a 100-yard kickoff return touchdown. "Collin was still a leader. He was on the sideline getting us going, especially when things weren't going our way. That's what I like about him."
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.
Cowboys coach Mike Gundy likewise refused to discuss his quarterback's injury.
"I'm really disappointed in myself, in our coaches, in the way we played," Gundy said. "You travel on the road, and you play a good football team, and you turn the ball over, you're poor on special teams and you don't tackle well, you essentially don't give yourself a chance to win."
Allen Chapman picked off three passes, returning one for a touchdown, and John Hubert added a pair of TD runs as the Wildcats (9-0, 6-0 Big 12) moved ever close to a Big 12 title.
Perhaps a national title, too.
They began the day second in the BCS standings behind only Alabama, which squeaked past LSU, and ahead of fellow unbeaten teams Notre Dame and Oregon.
"I'm proud of our guys because I think they've held up under the pressure," Snyder said, "because it increases as you go on."
Kansas State ended the Cowboys' three-game winning streak and lock up its first win over them since 2006. The Wildcats have scored at least 44 points six times this season, and this time did it against a team that had allowed 38 total over its last three games.
