The NBA All-Star made the choice to make a social statement back in February on Super Bowl Sunday. Brown showed up at the TD Garden wearing a No. 7 jersey with the message "#ImWithKap" on it. It was a message of support for the former NFL quarterback.Jaylen Brown wearing a Kaepernick jersey on Super Bowl Sunday this year.

The former second-round pick has been an advocate for racial and social justice during his time away from the NFL.Why Colin Kaepernick hasn't played in the NFL since the 2016 seasonBack in the preseason of the 2016 campaign, Colin Kaepernick took a kneel for the first time. The then-San Francisco 49ers quarterback was protesting racial injustice and police brutality taking place in America. In his final season in the NFL, Kaepernick threw for 2,241 yards, 16 touchdowns, and four interceptions. The 49ers decided not to renew the quarterback's contract after that season.Back in May, the former University of Nevada star worked out for the Las Vegas Raiders in hopes of an NFL return. However, Kaepernick hasn't gotten the call to play this season.The question remains as to whether we will see the quarterback suit up again in the NFL. Given that the league has softened its stance on him, there is a chance. Time will tell if Colin Kaepernick will be welcomed back.
