Many stood, some knelt and some heard boos.

The Seattle Seahawks were on the field for the national anthem before their game on Sunday night against the Indianapolis Colts, but a group of six players, led by Michael Bennett and Cliff Avril, sat on the bench for the duration of the song. The rest of the Seahawks were standing, scattered on the sidelines in a far more disorganized grouping than most teams have chosen, while the Colts were on the sidelines with locked arms. Andrew Luck, the injured Colts quarterback, was shown during the NBC broadcast singing along to the song.

Rather than wait in the locker room, like they did during last week’s anthem, the Seahawks decided instead to create a fund with the goal of building a more compassionate and inclusive society, calling it the Players Equality & Justice for All Action Fund.

Here is a quick look at what each team did during the playing of the national anthem on Sunday:

■ A group of about 30 San Francisco 49ers players knelt during the anthem, and the rest of the team stood behind them. They were joined on the field by the team’s general manager, John Lynch, and all of the players — kneeling and standing — had their hands on their hearts. It was the first game the 49ers have played since President Trump’s incendiary comments, which were inspired by the actions of the former 49er Colin Kaepernick, and the team made one of the more dramatic statements of either week. A smattering of boos could be heard as the 49ers took a knee. All of the Cardinals players were standing for the song.
