(ASSOCIATED PRESS) — Kansas City cornerback Marcus Peters raised a black-gloved fist during the national anthem before the NFL opener against San Diego, backing up his promise to show support for protests started by Colin Kaepernick .
It was the only such gesture visible throughout the early games Sunday, as the anthems took on more significance because of the 15th anniversary of Sept. 11 attacks. The Seattle Seahawks said last week they planned a demonstration of "unity" when their game against Miami kicks off Sunday afternoon.
Several teams, including the Chiefs, saw their players link arms during the anthem. Peters, the 2015 Defensive Rookie of the Year, was the last person in the Chiefs' line and had his arm free to raise it.

Peters said he was "100 percent behind" Kaepernick, who chose to sit and take a knee during the anthem in preseason games to call attention to what he termed the oppression of blacks and other minorities.
