About two dozen players, including Baltimore Ravens linebacker Terrell Suggs and Jacksonville Jaguars running back Leonard Fournette, took a knee during the playing of the national anthem before the start of the teams' game at Wembley Stadium on Sunday.
Other players on one knee during the performance included Ravens linebacker C.J. Mosley, wide receiver Mike Wallace and safety Lardarius Webb as well as Jaguars linebacker Dante Fowler, defensive tackle Calais Campbell, defensive end Yannick Ngakoue and cornerback Jalen Ramsey.
Players on both teams and Jaguars owner Shad Khan, who were not kneeling, remained locked arm-in-arm throughout the playing of the national anthem and "God Save The Queen," the national anthem of Britain.
No players were kneeling during the playing of the British national anthem.
President Donald Trump had a suggestion on Saturday for National Football League owners whose players decide to take a knee during the national anthem: fire them.
