MANHATTAN, Kan. (AP) – Kansas State quarterback Collin Klein spent the final 25 minutes of Saturday night’s win over Oklahoma State watching from the sideline, the coaching staff having taken away his helmet to keep him from trying to get back in the game. The Heisman Trophy frontrunner and undisputed catalyst for the third-ranked Wildcats had just sustained an undisclosed injury in the third quarter of a 44-30 victory. Even his teammates weren’t sure how badly he was hurt – or how long he’ll be out. Longtime coach Bill Snyder deftly sidestepped every question posed about the Wildcats’ most indispensable player. He at first joked he was trying to give backup Daniel Sams some experience, and then conceded that Klein had been hurt at some point during the third quarter.
