Klein was taken out of the game against the Cowboys for undisclosed reasons, but signs point to a possible concussion.

What's At Stake?
There's still time for other teams to catch Kansas State in the Big 12, but it would take a minor miracle given the way Collin Klein and the Wildcats have been playing.
Plus, the Big 12 title is only one of Kansas State's goals. The Wildcats (9-0, 6-0 Big 12) are also ranked No. 2 in the nation, meaning they have a shot at playing in the BCS Championship Game.
The last time Kansas State won the Big 12 was in 2003.
TCU (6-3, 3-3 Big 12) is going bowling this season. This is the program's first season in the Big 12. The Horned Frogs won the MWC title the last three years.

What They're Saying
All the buzz at Kansas State is surrounding the status of senior quarterback and Heisman favorite Collin Klein.
Klein left Week 10's game against Oklahoma State with an undisclosed injury, but Dan Wetzel of Yahoo! Sports reported on Sunday that he was taken out of the contest due to a possible concussion.
Klein's status is critical to the Wildcats' chances of making it to the BCS Championship Game.
TCU is coming off a thrilling 39-38 double-overtime victory over West Virginia. Junior receiver Josh Boyce got a Big 12 game ball from ESPN, registering six catches for 180 yards and two touchdowns, including a 94-yard touchdown that sent the game into overtime.
You'll remember that TCU was the victim of a 56-53 triple-overtime loss to Texas Tech on Oct. 20.
Kansas State Player to Watch: Collin Klein, QB
There is still no telling whether Klein will play in this game, but I'm going on a hunch that he will make it, especially with Kansas State's championship dreams on the line.
Klein is widely considered to be the Heisman favorite. He's averaged 10.1 yards per pass attempt (tied for first in the nation) and 12 touchdowns to two interceptions in the process.
On top of that, he's rushed for 698 yards and 17 touchdowns while leading the Wildcats to victories over Oklahoma, West Virginia, Texas Tech and Oklahoma State.
TCU Player to Watch: Josh Boyce, WR
Josh Boyce leads the Horned Frogs in receptions (50), receiving yards (687) and receiving touchdowns (seven) this season.
The junior's performance against West Virginia was a big reason why TCU stunned the Mountaineers in Morgantown.
Key Matchup: TCU Passing Game vs. Kansas State Pass Defense
Kansas State is inevitably going to score its fair share of points, if Collin Klein is ready.
That means TCU has to keep up.
The Horned Frogs have had more success passing the ball this season than running it, even with freshman quarterback Trevone Boykin in place of the injured Casey Pachall.
Kansas State doesn't have a bad pass defense, but the Wildcats still give up more through the air than on the ground.
Boykin and the rest of the Horned Frogs need to step up in this one.
Prediction: Kansas State 40, TCU 23
Assuming Collin Klein is available, I could see the Wildcats posting 40 big ones on TCU. The Horned Frogs have allowed a combined 103 points in regulation in their past three games.
Plus, Kansas State has a much better defense than the likes of West Virginia, Oklahoma State and Texas Tech.
