The NFL has seen unprecedented protests across games in the wake of Donald Trump's opposition to the act started by Colin Kaepernick
This week's NFL schedule was more notable for what happened before the games than during them.
A number of players - and in some cases entire teams - either took a knee during the singing of the American national anthem before kickoff or declined to take to the field for the pre-game ceremony entirely.
They did so to protest racial injustice in American society by following the lead of former San Francisco 49ers quarterback Colin Kaepernick, who was the first player to go down on one knee during the anthem last season.
