By Mark Lamport-Stokes LOS ANGELES (Reuters) - Los Angeles Rams defensive end Robert Quinn raised his fist and San Francisco 49ers backup quarterback Colin Kaepernick was among several players who knelt during performances of the U.S. national anthem on Sunday. Three Miami Dolphin players also 'took a knee' before their game against the New England Patriots as public protests continued in the National Football League aimed at drawing attention to racial inequality. Kaepernick started what has become a controversy when he began the gesture against injustice and police brutality by refusing to stand for "The Star-Spangled Banner" during preseason games.
