“Hitting the (NFL) with the advertisers is the only way to hurt them.”

Comedian Amy Schumer is taking a stand in solidarity with football star Colin Kaepernick and the protest movement he started in 2016, announcing that she would not appear in any ads during the upcoming Super Bowl in February.

She also called on white National Football League (NFL) players to follow Kaepernick’s lead and kneel during the national anthem in protest against social injustice and police brutality against African-Americans, as he has.

“I personally told my reps I wouldn’t do a Super Bowl commercial this year,” Schumer explained on Instagram. “I know it must sound like a privilege ass sacrifice but it’s all I got. …Hitting the [NFL] with the advertisers is the only way to hurt them.”

Schumer had previously appeared in a Bud Light Super Bowl ad two years ago.

“Otherwise, how are you not complicit?” Schumer continued. “Stand up for your brothers and sisters of color.”

She’s the latest entertainer to join Kaepernick’s protest through the national platform of professional football: multiple reports earlier this week revealed that Rihanna turned down an invitation to perform at the upcoming halftime show.

The NFL and CBS, who owns the rights to air the Super Bowl, have not confirmed these reports.

Prior to that, pop group Maroon 5 had been rumored to be the headliner of next year’s halftime show. The group has not made any comment on the sudden burst of politics surrounding the upcoming game.

Kaepernick initiated the protest in 2016 when he was the San Franciscio 49ers’ quarterback, kneeling on one knee during the national anthem that precedes each game—sparking a movement that followed.

President Donald Trump’s criticism of NFL players during a 2017 Alabama rally sparked massive player protests throughout the 2017 season.

Kaepernick has been out of the league since and was a voluntary free agent after the 2016 season, but was subsequently not signed by any team.

He has filed a collusion lawsuit against the NFL, blaming his political stances for not being allowed to play.

This season, three NFL players—the Carolina Panthers’ Eric Reid and Miami Dolphins’ Kenny Stills and Albert Wilson—have kneeled during the anthem.

Powerhouse athletic brand Nike also embraced Kaepernick in an ad last month that sparked controversy.
