Povetkin won the vacant WBA crown in August 2011 by defeating Ruslan Chagaev in a unanimous points decision in Erfurt, Germany. He defended it by knocking out U.S. challenger Cedric Boswell in the eighth round in Helsinki in December.
Huck (34-2-0, 25 KOs) defended his WBO title eight times before unexpectedly moving to the heavyweight division and challenging Povetkin.
Despite his debut as a heavyweight, Huck showed a brave performance challenging the Russian champion at every opportunity.
