Kansas State quarterback Collin Klein's injury raised fears of a concussion on Saturday, prompting him to be removed from the Wildcats' 44-30 victory over Oklahoma State, Yahoo's Dan Wetzel reported Sunday night.

Klein was taken out of the game after a third quarter drive in which he was hit especially hard on numerous plays. The drive went for eight plays and 93 yards before Klein scored on a 1-yard quarterback sneak. Afterward on the bench, Klein was evaluated and did not remember certain details from the drive, Wetzel reported.

He never returned to the game, which was already firmly in Kansas State's grasp when he left. But he did stay on the sidelines, according to Wetzel.

More from Wetzel's report:

Kansas State media relations director Kenny Lannou said Sunday afternoon the school had no update on Klein.

"He obviously was injured or we wouldn't have taken him out," [head coach Bill] Snyder said Saturday night.

The level of concussion – if there was one at all – and the status of the Heisman Trophy candidate for Saturday's game at Texas Christian is unknown.
