Lynch had decided to stand for a game against the Los Angeles Rams on Monday night, reports AP, however he didn't stand for a single 'Star Spangled Banner' for the whole of last season, despite never giving a reason why.
No other players decided to protest during the anthem, however The Hill reports that three Miami Dolphins players protested during the national anthem on Sunday before their season opener against Tennessee.
Last year, president Trump slammed Lynch on Twitter for his protest. Taking to the social media platform in November, he wrote:
Marshawn Lynch of the NFL’s Oakland Raiders stands for the Mexican Anthem and sits down to boos for our National Anthem. Great disrespect!
Despite Lynch's protest, there were no other visible protests by other NFL players before the NFL season opener between the Atlanta Falcons and Philadelphia Eagles last week.
The NFL reportedly won't implement a new policy this season on players standing during the national anthem, after players taking a knee during the Star Spangled Banner to protest police brutality and racial inequality in the United States.
In May, NFL owners reportedly voted for a policy that stated players should 'stand and show respect', however, a legal challenge from the players' union froze the policy.
