Hours earlier, college football players for Michigan and Michigan State, along with a group of students at North Carolina, raised their fists during the playing of "The Star-Spangled Banner" on Saturday.

Since 49ers quarterback Colin Kaepernick refused to stand for the Anthem before NFL preseason games, citing racial injustice and police brutality, his movement has slowly spread across fields and courts in the U.S. On Saturday, college and professional athletes joined together to follow his lead after a week punctuated by riots in Charlotte, N.C., and the killing of an unarmed black man in Tulsa, Okla.

This wasn't the first time Boyd sat during the anthem. She said she also did it at the last few games.
