Colin Kaepernick is the new face of Nike's 30th-anniversary "Just Do It" campaign, which includes his picture above the following message: "Believe in Something".
The source says Nike will feature Kaepernick on several platforms, including billboards, television commercials and online ads.
Others who support Kaepernick will gladly shift their dollars to Nike for its support of the former San Francisco 49ers quarterback, who is viewed as a hero to many for standing up for social issues even if it meant the National Football League ultimately would freeze him out. "Even if it means sacrificing everything", accompanied by the hashtag #JustDoIt.
Nike signed Kaepernick in 2011 and kept him on its endorsement roster over the years, ESPN reported.
Fans have already taken to Twitter to slam the ad campaign, often using the argument that sport stars and apparel companies shouldn't be getting into political issues.
The NFL this season has adopted a rule requiring all players to stand during the anthem, although it gave them the option of staying off the field until the ceremony was over.
An arbitrator is sending Kaepernick's grievance with the NFL to trial, denying the league's request to throw out the quarterback's claims that owners conspired to keep him out of the league because of his protests of social injustice.
That policy has yet to go into effect as negotiations between the league and the players' union over the policy continue.
Kaepernick, the former NFL quarterback at the centre of a raft of legal cases that's nearly assuredly going to rattle the very core of the league's institutional whiteness, was not only revealed to be the face of the campaign, but a very well-paid one at that.
