Nike selected the controversial former San Francisco 49ers quarterback Colin Kaepernick as the new face of the athletic wear company’s “Just Do It” campaign, which is celebrating its 30th anniversary.

The now-free agent quarterback, who led the Niners to Super Bowl XLVII where they fell to the Baltimore Ravens, stirred up controversy when he began kneeling during the playing of the national anthem prior to NFL games, beginning in the summer of 2016, to protest racial injustices against the African-American community. Many other players have joined the movement since it began, which eventually led to NFL owners voting to enact a national anthem policy for the 2018 season. Under the new guidelines announced in May, players and others associated with the NFL who are on the sidelines must stand during the playing of the Star Spangled Banner, while those who choose not to stand must remain in the locker room. However, the NFL put the policy on hold in July amid negotiations with the NFL Players Association.
