The Cardinals, however, opted to remain in the locker room before the game.
The NFL this season has pushed to help spread awareness of social injustice. Among other initiatives, the 49ers feature the following phrases in each painted end zone boundary line: "End Racism" and "It Takes All of Us."
Players have the option to wear helmet decals with names/initials of victims of systemic racism or one of four phrases: "It Takes All of Us," "End Racism," "Stop Hate," or "Black Lives Matter." Coaches have the option to wear patches with the same.
49ers players had the option to wear custom-made Black Lives Matter shirts provided by Levi's during pregame, which many did.
