Colin Kaepernick is eight seasons removed but his last NFL action, but he still won't close the door on a possible return. During the 2016 season, the former San Francisco 49ers quarterback peacefully protested against racial inequality and police brutality by kneeling during the national anthem.

Kaepernick has been vocal about his desire to join an NFL team, sending messages to squads, posting videos of him training and making it known that he believes he's still in football shape. Back in August, Kaepernick mentioned that he was still full steam ahead on staying ready.
