On a night that was supposed to be significant for what 49ers quarterback Colin Kaepernick did on the field, what he didn’t do while off the field will create even bigger headlines.

During the playing of the national anthem, Kaepernick sat.

The 49ers have confirmed that Kaepernick did not stand for the anthem, and they have issued the following statement.

“The national anthem is and always will be a special part of the pre-game ceremony,” the team said in a statement issued to PFT. “It is an opportunity to honor our country and reflect on the great liberties we are afforded as its citizens. In respecting such American principles as freedom of religion and freedom of expression, we recognize the right of an individual to choose to participate, or not, in our celebration of the national anthem.”

It’s unclear why Kaepernick sat. However, Kaepernick retweeted the following message on Thursday, which accompanied images of the American and Confederate flags: “The fact that you really believe that there is difference in these flags means that your [sic] ignoring history.”

At a time when NFL players are criticized for not speaking out on social issues, Kaepernick has provided a very significant and conspicuous gesture. As the team noted, it’s his right to do so. But given that Kaepernick opted to make a stand by sitting during the traditional pregame honoring of the country and its flag — which is so tightly woven into the DNA of the NFL — there surely will be a reaction.
