The Seahawks and Titans say they will both sit out the national anthem before Sunday's game in Nashville.
The Seahawks released a statement from their players about 30 minutes before kickoff at the Titans' Nissan Stadium saying the team would not participate in the anthem. It did not specify whether the team would remain off the field while the "Star Spangled Banner" is played, and the statements followed up shortly thereafter with one of their own.
"As a team, we have decided we will not participate in the national anthem," the statement read. "We will not stand for the injustice that has plagued people of color in this country. Out of love for our country and in honor of the sacrifices made on our behalf, we unite to oppose those that would deny our most basic freedoms. We remain committed in continuing to work towards equality and justice for all."
The Titans' statement read: "As a team, we wanted to be unified in our actions today. The players jointly decided this was the best course of action. Our commitment to the military and our community is resolute and the absence of our team for the national anthem shouldn't be misconstrued as unpatriotic."
Seahawks players, led by Michael Bennett, have been outspoken in their support of the movement to protest police brutality started last year by then-49ers quarterback Colin Kaepernick.
The team and owner Pete Carroll released statements Saturday night supporting the players after President Donald Trump said at a rally Friday and repeated on Twitter that those who kneel during the anthem should be "fired."
Earlier Sunday, the Steelers spent the national anthem in the locker room with the exception of U.S. Army veteran Alejandro Villanueva, who stood at the edge of the tunnel with his hand over his heart.
