Pittsburgh Steelers safety Troy Polamalu admitted he has lied about head injuries to stay in games.
"Yes, I have, for sure," Polamalu told the Dan Patrick Show, noting that he has also chosen to stay in games against the medical staff's wishes.
Polamalu didn't tell any "major lies" when it comes to concussions, but said football players see a difference between a blow to the head that forces a player from a game and a lighter one that doctors see as a concussion.
"I've had, I believe, eight or nine recorded concussions. We'll have another conversation after I'm done playing football," Polamalu said on the show. "When you get your bell rung they consider that a concussion -- I wouldn't ... If that is considered a concussion, I'd say any football player at least records 50 to 100 concussions a year."
More than 2,400 retired NFL players are now plaintiffs in a lawsuit that accuses the NFL of hiding the knowledge that repeated concussions could lead to brain damage.
Still, Polamalu is the latest current player to admit a willingness to conceal a head injury. Chicago Bears linebacker Brian Urlacher said in February that he would lie about a concussion to stay on the field.
