Former 49ers safety Eric Reid has joined Colin Kaepernick in filing a collusion grievance against the National Football League.
Reid, 26, was one of the first players to join Kaepernick in kneeling during the national anthem to protest racial injustice and he remains unsigned after becoming a free agent when his contract with the 49ers expired after last season.
