San Francisco 49ers quarterback Colin Kaepernick knelt again yesterday as the national anthem played before his team faced off against the Tampa Bay Buccaneers, continuing his protest against injustices toward minorities and inspiring others to follow.

Miami Dolphins running back Arian Foster began kneeling during the pregame anthem on Sept. 11 and has been a vocal supporter of Kaepernick ever since. “I don’t even think the song should be our national anthem, because it’s a racist song, if you look at the other verses of it,” he told VICE News correspondent Jay Caspian Kang.

Even some high school football players have participated in the protest. “I think it’s a beautiful thing,” Foster said.

The movement shows no signs of slowing down, as similar protests have recently been made by cheerleaders, marching bands, and basketball teams. “What would have to happen for me to stand for the national anthem?” Foster asked himself. “Honestly, man, I’m not sure I will stand again.”
