A report that Cincinnati Bengals wide receiver Chris Henry had chronic traumatic encephalopathy, a form of degenerative brain damage, at the time of his death, has rattled Seattle Seahawks wide receiver Sean Morey, Alan Schwartz of the New York Times reports.

"It's very emotional to hear--it rattles me," said Morey. "The fact that this has been found (in) guys (you) played against last year, an active player, I think it's sobering. You have to ask yourself how many are playing the game today that have this and don't even know about it.

"We have to educate the players," Morey said. "The players have to have the ability to have informed consent."

A Pro Bowl-caliber special teams player, Morey was mamed co-chair of the NFL Players Association concussion and traumatic brain injury committee last October. Despite taking a leadership role in that area of the game, Morey admitted to playing in a game last season, despite knowing he had a concussion.

Morey won't publicly admit to the number of concussions he's sustained during his career, but told the Associated Press that it's "more than I'd like to admit".

Morey, 34, signed a three-year contract with the Seahawks this off-season.
