A Colorado credit union has parted ways with Denver Broncos linebacker Brandon Marshall following his actions Thursday.

Marshall took a knee during the National Anthem before the NFL's season opener – joining Colin Kaepernick in a protest that has garnered national attention.

"Although we have enjoyed Brandon Marshall as our spokesperson over the past five months, Air Academy Federal Credit Union (AAFCU) has ended our partnership," credit union president Glenn Strebe said in a statement on Facebook. "AAFCU is a membership-based organization who has proudly served the military community for over 60 years. While we respect Brandon’s right of expression, his actions are not a representation of our organization and membership. We wish Brandon well on his future endeavors."

Marshall had previously expressed support for Kaepernick during an interview with the Colorado Springs Gazette. He says his family and teammate Virgil Green were the only ones who knew about his plan to kneel.

“The message is that I’m against social injustice,” Marshall told reporters after the game. “I’m not against the military, police or America at all. I’m against social injustice and I feel like this is the right thing to do.

“I feel like this is the right platform. This is our only platform you know, to really be heard, and I feel a lot of times, people want us to just shut up and entertain them, shut up and play football.”

Marshall and Kaepernick both attended the University of Nevada – Reno. Marshall says he knew that the protest would draw attention – but that didn’t stop him.

“I knew what territory it came with, and I decided to do it,” Marshall said. “Some people did decide not to, but I did.”

The Broncos issued the following statement on Marshall’s protest:

“While we encourage members of the organization to stand during the Anthem, we understand, respect it’s a personal decision.”

Marshall said he’s donating an “undisclosed” sum of money to programs for veterans and other charities.

“Honestly, I’m a man of faith,” Marshall said, “so I prayed about it long and hard, and I feel like it was the right thing to do.”
