According to reporter Shaun King, the NFL is working to make it a requirement for players to stand for the national anthem:

The news comes after Donald Trump's explosive comments on national anthem protests:
"Wouldn't you love one of these NFL owners... when someone disrespects our flag say, "Get that son of a bitch off the field, right now, out, he's fired."
The NBA has a rule requiring players, coaches and trainers to all "stand respectfully" for the anthem, and teams "do not have the discretion to waive this rule."
Some teams have stood with locked arms during the anthem during the preseason, but it will be interesting to monitor whether some stars decide to kneel once the regular season begins.
NFL, NBA and MLB athletes have responded with either comments pushing back against the president or reactionary statements such as kneeling or staying in the locker room.
Those players involved Marshawn Lynch, Baltimore Ravens players and Miami Dolphins players.
Roger Goodell sent out a memo and team owners reportedly had a rejected idea ahead of the games.
We'll see if things change heading into Week 5 of the 2017-18 NFL season.
