What’s news around health and safety in football:

* The latest college football news, according to ESPN.com, involves Kansas State quarterback and Collin Klein, who suffered an injury Saturday night against Oklahoma State that may or may not be a concussion. Yahoo!Sports reported he sustained a concussion, citing sources close to the 8-0 team.

Afterward, Klein was evaluated on the bench by Kansas State trainers and, a source said, could not recall the details of the drive, including the fact he scored. His helmet was immediately taken away and he did not return to the game. Kansas State led 38-17 at the time. Klein remained on the sideline the rest of the game, however, interacting with teammates and even trying to vocally motivate them. Coach Bill Snyder offered no details on the injury after the game.

ESPN.com reported Monday that Klein’s mom said “he looks great” after seeing him Sunday.

“He looks great and he feels great,” Kelly Klein said. “I think he is going to be 100 percent this week. As far as I know he will begin a normal film review and normal practice week as per usual.” Kelly Klein said only trainers would address if her son suffered a concussion, and she wasn’t certain.

Bill Snyder said Monday that Klein “looks fine to me,” according to the Topeka Capitol-Journal.

Will he play Saturday against TCU? ”I hope so,” he said. Do you know? “I hope so. I hope they all play,” he replied. Snyder guards injury information like a government military secret, and when it concerns his Hesiman Trophy candidate quarterback he will be even more protective.

* The Magnolia Reporter wrote about an Arkansas high school football player who collapsed on the field last Friday night after coming back from a concussion two weeks earlier. He is still unresponsive.

* Oakland Raiders coach Dennis Allen said both X-rays and an MRI came back negative on running back Darren McFadden’s ankle, according to NFL.com. He might play Sunday against the Baltimore Ravens.

* NFL.com reported that Jordy Nelson could return this week from an ankle injury, but the Green Bay Packers could be without linebacker Clay Matthews for a few weeks with a sore hamstring.
