Former NFL San Francisco 49ers star quarterback Colin Kaepernick held a workout on Saturday at the Charles R. Drew High School south of Atlanta in front of NFL scouts and members of the media. Kaepernick’s workout came after a week of contentious negotiations with the NFL, which Kaepernick has accused of blackballing him for “taking the knee” during the national anthem as a protest against police violence and racism. Kaepernick’s move sparked racial justice protests that swept across the NFL and other major professional sports leagues, but resulted in him not being signed by a single NFL team and being out of the league for three years. On Saturday, Kaepernick refused to participate in the NFL’s hastily arranged workout, which was to be closed to the press. Instead, he went to a nearby high school and held his own workout, which one of the NFL scouts called “impressive.”
