The Seattle Seahawks released a statement saying that the team will not be on the field for the national anthem on Sunday.
The Titans released an official statement on the players' decision, saying that the players chose to do this as a team.
We're not participating in the anthem today - not to be disrespectful to the anthem, but to remove ourselves from the circumstance.
Players from both teams remained in their lockers rooms during the song in a joint protest.
If a player wants the privilege of making millions of dollars in the NFL, or other leagues, he or she should not be allowed to disrespect.
They also noted that the decision was made "out of love for our country and in honor of sacrifices made on our behalf".
The Steelers did not protest the anthem previous year and had stayed relatively neutral on the national discussion, but President Donald Trump's verbal attack on NFL players who protest appears to have changed things.
During the early afternoon NFL games today, the national anthem singer at the Detroit Lions-Atlanta Falcons game kneeled and raised his fist at the end of his performance. Commissioner Roger Goodell, who has taken heat for quarterback Colin Kaepernick's struggle to find a team, quickly condemned Trump's comments. Standing with locked arms is good, kneeling is not acceptable.
"We're not going to play politics. Our players completely respect the military and veterans of our country; however they feel these issues need to come to the forefront", the statement read. By the second game, center Justin Britt has stood beside him during the anthem with his hand on Bennett's shoulder.
