Colin Kaepernick billboard hangs high above Nike store in San Francisco's Union Square

SAN FRANCISCO, California -- Former San Francisco 49er Colin Kaepernick is dominating conversations across the U.S. as well as the San Francisco skyline.

Video shows a giant billboard on top of Nike's flagship just off Union Square.

The move comes a day after the company announced that Kaepernick would be a major part of its 30th anniversary "Just Do It" campaign.

The billboard features the caption, "Believe in something, even if it means sacrificing everything," which is a reference to Kaepernick's protests against racial injustice, that he and others believe has cost him a job in the NFL.
