Today’s health and safety news centers around a few recovering NFL players:

* Kansas City Chiefs quarterback Brady Quinn admitted he tried to play through his second concussion last month, the Associated Press reported.

He never saw the Raiders’ Rolando McClain while getting sacked later in the first quarter, perhaps augmenting the severity of the initial concussion, and recalled having “tunnel vision” and being unable to see the Oakland defensive backs when he threw an interception. It was at that point Quinn was removed from the game. “That’s why I tried to stay in the game, because it was the first opportunity for me in a while,” said Quinn, speaking for the first time since the injury. “I tried to play through it, and that’s my fault for not being smart about it.”

* The Florida Times-Union reported that wide receiver Laurent Robinson is trying to work his way back from his third concussion this season suffered last month.

* ESPN reported that KJ Wright and James Carpenter of the Seattle Seahawks are still sidelined with concussion symptoms.

* New Orleans Hornets coach Monty Williams told NOLA.com his comments about the NBA’s concussion policy were inappropriate — after he was fined $25,000 by the league.

* RantSports.com wrote there are Heisman Trophy implications if Kansas State University admits quarterback Collin Klein suffered a concussion.

* The Bleacher Report said the NCAA should have a mandatory sit-out rule for players who suffer concussions.

* WXIN-TV in Indianapolis profiled Bill Simpson’s auto racing helmet company where they’re trying to make a safer football helmet.

* The Montreal Gazette gave a thumbs up review to hockey player Keith Primeau’s book about coping with concussions.

* The Kenyon Collegian reported that college rugby is now eligible for NCAA-sponsored concussion screening.
