Sales of Colin Kaepernick jerseys have soared in the past week since the San Francisco 49ers quarterback stepped into a national debate over systemic racism by refusing to stand during the national anthem.

As of Sunday, Kaepernick‘s $99 jersey was the top-seller among current players on the 49ers online store, and ranked No. 5 overall on the NFL’s store. Just over a week ago, before the controversy, Kaepernick — currently a backup quarterback — was ranked 20th on the 49ers site, as Seattle Times reporter Mike Rosenberg first pointed out.
