The entire Garfield High School football team and its coaching staff knelt during The Star-Spangled Banner before the Friday kickoff against West Seattle High School in Seattle. Players and coaches plan to continue kneeling all season, Thomas said in a video posted by KCPQ-TV.
It was the first time Garfield football players participated in the increasingly popular demonstration.
West Seattle athletes began kneeling a week prior after getting approval from administration staff.
Thomas told Seattle media outlets his players have encountered either police brutality or racial profiling while also dealing with a racially divided school.
