New England Patriots fans booed the 17 Patriots players who knelt during the national anthem; the crowd of more than 60,000 shouted at the athletes to "stand up!"
The boos were loud and continued throughout national anthem's duration, MassLive reported.
Players across the NFL protested Sunday, after President Donald Trump, speaking at a rally Friday, encouraged people in Alabama to leave the game if players showed disrespect toward the U.S. flag and national anthem.
“... If you see it, even if it's one player, leave the stadium, I guarantee things will stop,” Trump said. “Things will stop. Just pick up and leave. Pick up and leave. Not the same game anymore anyway.”
Later in his speech, Trump ignited further controversy, saying that he wished NFL owners would take a more aggressive response to athletes who protest the Star Spangled Banner.
“Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, ‘Get that son of a bitch off the field right now,'” Trump exclaimed. “'Out. He's fired. He's fired!’”
The Patriots’ players who protested the national anthem on Sunday included James White, Stephon Gilmore, Brandin Cooks, Lawrence Guy, Alan Branch, Malcom Brown, Malcolm Butler, Brandon Bolden, Devin McCourty, Trey Flowers, Deatrich Wise, Jonathan Jones, Elandon Roberts, Duron Harmon, Adam Butler, Jordan Richards, Johnson Bademosi.
