NFL players are still open to lying to their respective teams about whether or not they have suffered a concussion. "The bottom line is: You have to be able to put food on the table. No one's going to sign or want a guy who can't stay healthy. I know there will be a day when I'm going to have trouble walking. I realize that," Jaguars running back Maurice Jones-Drew said. "But this is what I signed up for. Injuries are part of the game. If you don't want to get hit, then you shouldn't be playing." In a series of interviews about head injuries with The Associated Press over the last two weeks, 23 of 44 NFL players -- slightly more than half -- said they would try to conceal a possible concussion rather than pull themselves out of a game. Some acknowledged they already have.
