Nike's controversial 30th anniversary ad campaign featuring Colin Kaepernick might not have happened as the sportswear company nearly dropped him, according to a report in The New York Times.

Kaepernick was unemployed after leaving the San Francisco 49ers at the end of the 2016 season, having made headlines for kneeling during the national anthem in protest against police brutality towards African-Americans in the U.S., a move that other players replicated.
