Kaepernick spent the entirety of his six-year NFL career with the San Francisco 49ers. When he began taking a knee before games while playing for the San Francisco 49ers, the 34-year-old became the focus of national attention. He was protesting police brutality and institutionalized racism, and he did so while representing the 49ers.
Despite entering the NFL free agency market in 2017, he was never signed by a team anywhere in the league. As a result, Kaepernick filed a grievance with the NFL, alleging that the league's owners were conspiring to play tic tac toe have him suspended.
