DENVER — Broncos linebacker Brandon Marshall took a knee during the national anthem before Sunday’s game against the Indianapolis Colts at Sports Authority Field at Mile High.

Marshall created controversy when he decided not stand during the playing of the national anthem before the regular-season opener against the Carolina Panthers on Sept. 8.

There were some boos at the stadium directed at Marshall when he took the knee.

After the decision by San Francisco 49ers quarterback Colin Kaepernick to kneel when the national anthem is played before football games, Marshall joined in, agreeing to protest what Kaepernick deems are wrongdoings against African Americans and minorities in the U.S.

Marshall has lost some lucrative endorsement deals because of his protest.

On Sept. 9, Air Academy Federal Credit Union said it was ending its relationship with Marshall. And on Monday, CenturyLink terminated its contract with Marshall.  And a sporting goods store canceled his in-store appearance.

Marshall said he is not against the military and not against the police.

The backlash has also included a Broncos fan, who burned his jersey in front of team headquarters in Englewood.

But Marshall said Monday he will not back down.

“I’m still doing what I believe in. It’s not going to make me lose sleep,” he said. “At the end of the day, I’m still going to play football but still do what I believe in.

“Everybody I talk to in the military, I know a lot of vets. People I see comment, they all support me. It’s everybody else that don’t support, people not in the military.”

On Tuesday, Marshall met with Denver police Chief Robert White.
