The NFL players’ union has filed a non-injury grievance on behalf of free agent safety Eric Reid. The NFLPA cites one team appearing “to have based its decision not to sign a player based on the player’s statement that he would challenge the implementation of a club’s policy prohibiting demonstration” during the national anthem.
