Civil rights groups and protesters gathered outside of the NFL headquarters in New York City on Wednesday to support Colin Kaepernick.
The "United We Stand" rally saw celebrities and civil rights organizations like the NAACP show up in solidarity with the athlete.
The former 49ers quarterback sparked criticism last year after he kneeled during the National Anthem to protest police brutality against African-Americans.
NAACP CEO and President, Derrick Johnson, says the football star is being blackballed by the NFL.
"No player should be victimized and discriminated against because of his exercise of free speech — to do so is in violation of his rights under the Constitution and the NFL's own regulations," Johnson told NBC News.
Kaepernick says he doesn't plan on kneeling forever.
“I don’t want to kneel forever,” Kaepernick told USA Today. “I want these things to change. I do know it will be a process, and it is not something that will change overnight. But I think there are some major changes that we can make that are very reasonable."
