Owners, players and commissioner Roger Goodell met in Manhattan this week to address the national anthem protests that have drawn the ire of Trump, who has demanded that the NFL require players to stand for the anthem.
"We want our players to be standing and we will continue to encourage them to get up", he said, adding that the members of the meeting had not discussed any possible sanctions against players knelt.
But, after a meeting Tuesday with union representatives and players, the league did promise to help support some of the causes targeted by the protesting players, including reform of the criminal justice system.
Members of the Facebook community are calling for a boycott of the NFL, as they speak out against the league for allowing the protest to continue for so long, especially when previous players have been dealt fines and other consequences for doing the same thing.
The comment that only "six or seven players" were involved in the protest struck many as curious. "Stand for the National Anthem".
The petition comes a one day after Trump criticized the National Football League for not passing a rule that would penalize players who don't stand for the anthem.
Former San Francisco 49ers quarterback Colin Kaepernick, who first popularized the gesture a year ago, said he settled on kneeling as a form of protest because it is widely seen as a gesture of respect.
Trump has repeatedly expressed disdain for the protests since a rally in September.
More players have begun kneeling since Trump criticized the practice, and some sympathetic teammates have linked arms with the kneelers while standing themselves.
For nearly a month, the american president is engaged in a standoff with the NFL players posing a knee on the ground during the national anthem. "We did not ask for that", Goodell said.
