Numerous players kneel to protest anthem and Trump comments in opening game

Numerous players from two teams kneeled early Sunday when the Baltimore Ravens faced the Jacksonville Jaguars in England.

All players and staff on both teams linked arms. A number of players on both teams took a knee during the national anthem. Jaguars’ owner Shad Khan also joined his players on the field.

Over the weekend, NFL players blasted Donald Trump for comments he made about those who protest the national anthem.

The NFL and players' union pushed back against the president's remarks, defending players rights to peacefully protest. Multiple team owners also defended their players' rights.

Trump refused to back down, tweeting multiple times over Saturday and Sunday that any player kneeling during the anthem should be fired.

The showdown may lead even more players to protest via gestures on the field, which would put the league and the broadcasters that show games in an awkward position.

Last season, free-agent quarterback Colin Kaepernick was the first to sit out the national anthem in protest of the treatment of African-Americans in America, especially at the hands of police officers.

Since then, numerous other players have protested in similar fashion. While some were said to be interested, no team picked up Kaepernick's contract this season, which some NFL insiders said may be due to his actions.
