Colin Kaepernick

San Francisco 49ers quarterback Colin Kaepernick dropped to one knee rather than stand during the national anthem at a preseason football game Thursday night. It's an extension of the protest Kaepernick began last week when he sat as the anthem played before an earlier game, declaring, "I am not going to show pride in a flag for a country that oppresses black people and people of color."

Daddy would not have liked Colin Kaepernick. Had the San Francisco quarterback refused to stand for the national anthem in my father's presence, Daddy would have fixed him in a stare that could freeze the blood in your veins. Then, to no one in particular — but to everyone within earshot — he'd give the young man a two-sentence lesson in patriotic etiquette.

"You stand during the national anthem," he'd say, punctuating his words with fire. "People died for that flag."

As players rose to stand for the national anthem at the 49ers-Packers game on Friday night, 49ers' quarterback Colin Kaepernick pointedly remained seated.

His gesture was to protest the treatment of African Americans and minorities in the United States, as he told NFL.com after the game. Kaepernick has remained sitting during the anthem "in at least one other preseason game," according to the site.

CenturyLink Field will be packed and louder than ever on Sunday evening. The Seahawks host the San Francisco 49ers in a much-anticipated match-up. 

KPLU sports commentator Art Thiel says this game may very well be a preview of the NFC championship battle this season.
