Klein Kansas State head coach Bill Snyder has kept Collin Klein's injury a top secret since last week's victory over Oklahoma St. 

However, all speculation suggests that Klein suffered a concussion but is expected to play this week versus TCU.

If Klein did indeed sustain a concussion, expect for the play calling to be a little more conservative this week, minimizing his scrambling down the field. 

With that said, retaining the No. 2 ranking the Wildcats currently hold just got a little more challenging.

Klein is the leading Heisman candidate due to his dual-threat abilities. His passing game is not flashy but it is sharp and he does not make many mistakes. His running game is probably just as, if not more, dangerous to defenses but if that gets restricted for caution, then Kansas State will definitely have a long day in Fort Worth.

This game has a feeling of a main event fight. In talking to many locals around TCU campus, the excitement and anticipation of a 12-round war is in the air. It is very rare to have an undefeated visitor at Amon G. Carter Stadium, especially this late in the season, which will likely result in a hostile home field atmosphere.

The Wildcats' ranking of No. 2 just adds fuel to the purple fire. TCU's purple, I mean. The Horned Frogs are 3-2 versus Kansas St. and have won the last three meetings but the last game was back in 1986. 

Here's what I make of this game:

Known for his defensive schemes, TCU head coach Gary Patterson will unveil several different packages to contain and keep pressure on a possible fragile Klein. Filling the gaps around the line of scrimmage and playing a spy-coverage to keep Klein in check, TCU will force and challenge the Heisman hopeful to beat them through the air with his 82nd-ranked passing offense. Klein's stats: 265 yards with a pair of TDs and another 35 yards rushing.

TCU receiver Josh Boyce had a great game last week versus West Virginia and another is highly likely. Having fellow standout WRs Brandon Carter and Sky Dawson commanding their own respectable coverage, Boyce is able to capitalize on many 1-on-1 plays, allowing the Frogs to keep drives going and threatening to score often. Boyce will have a big impact on the Frogs' success by collecting 120 yards and a TD.   

And the final score, you ask? Kansas St. 23 TCU 17  Here's why: As mentioned above, Kansas St. does not make many mistakes, and when they do happen to turn the ball over, they have yet to allow any points. On the contrary, TCU quarterback Trevone Boykin can be a loose cannon with his decision making. 

For as many good moments he has had this first season, he has had that many more bad moments. His 13 TDs have shown signs of promise in the future but his seven INTs have been costly. And it is in that manner that I believe will end the game where Boykin is trying to finish a game-winning drive and then throws the crushing game-ending interception to secure Kansas State's win and keep their No. 2 ranking in tact.
