The NFL Players Association announced it has filed a grievance challenging the league's new national anthem policy.
In May, NFL owners unanimously approved a new anthem policy that requires players to stand if they are on the field during the performance of the Star-Spangled Banner. The new policy gives players the option to remain in the locker room, if they want. The NFL subjects the teams to a fine, if a player or a member of team personnel does not show respect for the anthem.
Players have been kneeling, sitting and raising fists during the national anthem in an effort to raise awareness for racial and social injustice in America since Colin Kaepernick took a knee before a preseason game in 2016.
