Former Russian boxer Alexander Povetkin appears to have justified his home country's invasion of Ukraine in an Instagram post which refers to fighting against 'Nazism'.
Vladimir Putin ordered a military assault on neighbouring Ukraine in the early hours of Thursday morning and the conflict is ongoing.
Public figures across the world have voiced their defiance against the war, including sports stars, but Povetkin's views look to be very different.
