The San Francisco 49ers quarterback first sat through the anthem during a preseason game to show his support for people of color who are being oppressed in the United States. "While some may not have taken a knee or raised a fist, we have shared the desire to influence positive change", the statement read.
All of the other uniformed Dolphins players and their opponents, the New Orleans Saints, were standing, many with their right hands over their chests. Three teams - Pittsburgh, Seattle and Tennessee - did not take the field until after the anthem.
A statement from the 49ers said the team wanted to "speak up for those whose voice is not heard". "And I think it's disgraceful", he said, without elaborating. "Negative and disrespectful comments suggesting otherwise are contrary to the founding principles of our country, and we do not support those comments or opinions".
While NFL players around the league continued the "anthem protests" for a second straight week, a small school in Throckmorton County continued a tradition of honoring Old Glory.

The French champions are planning to offer Sanchez a £10million "welcome" bonus to convince him to sign with them in January. Manchester City are prepared to return, having missed out on his signature on deadline day last month.
The move is a departure from the actions of dozens of NFL players who have deliberately been kneeling during the national anthem in defiance of Trump's public scolding over the silent protests, which began over a week ago and haven't waned. In the days that followed the president issued a series of tweets reiterating his views and calling for a fan boycott of games.
On Tuesday, Mr Trump called on the league to ban players from kneeling in protest at games while the national anthem is played, tweeting: "The NFL has all sorts of rules and regulations". Nothing not one thing has happen, the only thing that has happen is these players are showing disrespect to the American flag and those who have died defending Americans of every color and race.
The players knelt last weekend in response to social injustice. When the National Anthem was performed, Kaepernick refused to stand. The number of team demonstrations, either before the anthem or during, decreased this week.
The right to protest was included in the Bill of Rights for a reason, just as the right to bear arms, the freedom of the press, and the right to petition the government for an address of grievances.
