San Francisco 49ers quarterback Colin Kaepernick has received a shit ton of flack for taking a knee during the National Anthem before an NFL game. His reasoning was protesting the police brutality and social injustices that have been going on. Well now, Kid Rock is dishing out some more haterade.

At a recent show in Boston, Kid Rock was performing “Born Free,” where he yelled out “Fuck Colin Kaepernick!” You can watch for yourself below. The diss comes around the 0:50 mark.
