The Tennessee Titans did not stand or kneel during the national anthem before their game against the Seattle Seahawks. Cameron Heyward, linebacker James Harrison and others, were involved in the discussion about Sunday's protest, one team source said.

They posted a statement on their website noting they want to be unified as a team with the players deciding jointly that staying inside was the best course of action. Meanwhile, the Pittsburgh Steelers players chose to stay in the locker room - except one - rather than come out for the anthem prior to their game against the Chicago Bears.
President Trump tweeted during the games to say he supported players standing with their arms locked, but not those who kneeled during the anthem. "He's fired. He's fired, '" Trump said. "You know, some owner is going to do that".
According to a statement released by the team, the Seattle Seahawks players did participate in national anthem ahead of their game in Nashville Sunday against the Tennessee Titans. "There is no better example than the incredible response from our clubs and players to the bad natural disasters we've experienced over the last month", Goodell said.
"Pete had a long meeting with some guys (Saturday) afternoon, and we had a long team meeting last night that was pretty emotional".
Trump's comments have only emboldened players around the league.
