National Football League
Kaepernick's name began trending on Twitter after the NFL aired a Super Bowl ad about ending systemic racism.
The NFL has resisted players’ efforts to peacefully protest police brutality ever since former quarterback Colin Kaepernick began kneeling during the anthem in 2016.
"Your favourite white boy was drafted second. I like players who were drafted first."
Some football players are kneeling before their preseason games - despite plans to crackdown on their protest by the NFL.
