Eric Reid described the NFL's social justice campaign using video of Colin Kaepernick kneeling while remaining unsigned as "diabolical."

Reid also remains a free agent.

Reid added that "Goodell uses video of Colin courageously kneeling to legitimize their disingenuous PR while simultaneously perpetuating systemic oppression, that the video he's using fights against, by continuing to rob Colin of his career. It's diabolical."

Reid's tweets came a day after Kaepernick called out the NFL's campaign.

"While the NFL runs propaganda about how they care about Black Life, they are still actively blackballing Eric Reid for fighting for the Black community," tweeted Kaepernick, the former San Francisco 49ers quarterback who has been out of the NFL since 2016. "Eric set 2 franchise records last year, and is one of the best defensive players in the league."

Reid and Kaepernick were included in a video played at each stadium Sunday that featured the song "Lift Ev'ry Voice and Sing," which was performed by Alicia Keys.
