Colin Kaepernick, the former N.F.L. quarterback who inspired a player protest movement but who has been out of a job for more than a year, has signed a new, multiyear deal with Nike that makes him a face of the 30th anniversary of the sports apparel company’s “Just Do It” campaign, Nike confirmed on Monday.
The first advertisement from Nike, one of the league’s top partners, debuted Monday afternoon, when Kaepernick tweeted it, assuring that his activism and the protest movement against racism and social injustice he started would continue to loom over one of the country’s most powerful sports leagues.
