Safety Eric Reid was among three San Francisco 49ers players who knelt during the national anthem before facing the Chicago Bears.
In all, eight players around the NFL made some sort of statement during "The Star-Spangled Banner" before the early games this afternoon.
Reid recently left a group of players negotiating with the NFL about the protests, saying that Philadelphia Eagles safety Malcolm Jenkins excluded Colin Kaepernick from meetings and asked about the possibility of ending demonstrations if the league made charitable donations.
Reid joined former 49ers QB Kaepernick in kneeling a year ago.
On Sunday, Reid, receiver Marquise Goodwin and nose tackle Earl Mitchell each took a knee during the national anthem in Chicago, while everyone on the Bears' sideline stood.
In Miami, a trio of Dolphins players knelt, as usual: Julius Thomas, Kenny Stills and Michael Thomas.
In Baltimore, Ravens rookie linebacker Tyus Bowser knelt in end zone for first few verses of anthem, then moved to the sideline and stood at attention for the rest, as he has done before.
The one Titans player who has been protesting by staying off the field, receiver Rishard Matthews, was inactive Sunday. He came onto the field after the anthem ended.
After the anthem ended, a trio of Titans players raised their fists overhead: Brian Orakpo, Jurrell Casey and Wesley Woodyard.
