Instant analysis: K-State 44, OK State 30

MANHATTAN, Kan. -- There was a noticeable lack of Collin Klein in the fourth quarter, but Kansas State survived a meeting with another Big 12 title suitor and top-25 opponent, dispatching Oklahoma State 44-30.

Klein was on the sideline without a helmet for much of the second half, and his Cowboys counterpart, Wes Lunt, reportedly suffered from concussion-like symptoms. He was sidelined after taking a big hit on his third interception of the night.

It was a rough night for quarterbacks but a good night for the BCS title contender. Kansas State took care of business against a pretty good Oklahoma State team. Let's take a closer look with some instant analysis:

It was over when: Allen Chapman intercepted Clint Chelf in the end zone with 2 minutes, 6 seconds remaining, ending a drive that featured a pair of fourth-down conversions.

Game ball goes to: Klein. He sat for much of the second half but was key as Kansas State took advantage of the Oklahoma State turnovers -- and had a vintage Klein game, despite the injury. In less than three quarters, he had 245 yards on 16-of-22 passing and 64 yards and a score on 17 carries.

Second game ball goes to: Chapman. Chapman had three interceptions on two quarterbacks, including the pick that sealed the game.

Stat of the game: Kansas State won the turnover battle 5-0. The yardage battle was fairly even, but you can't turn the ball over like that on the road and expect to win. K-State is plus-20 on the season in turnover margin. Entering this week, no team in the nation was better than plus-19.

Unsung hero of the game: Kansas State's kick-return team. Tyler Lockett and Tramaine Thompson broke kick returns of 100 and 60 yards, respectively, and Lockett scored on his. K-State turned Thompson's return into just three points with Klein out, but combined with the turnovers, this paid off big.

What it means: Kansas State will spend the week worried about Klein's health but not the Big 12 race. With three games left, Kansas State is the clear front-runner and already beat the only team with one Big 12 loss (Oklahoma) on its home field.

Plenty more to come tonight ...
