Johann Duhaupas

On a day's notice Duhaupas took on the fight against Russian fighter Alexander Povetkin, replacing the former WBC heavyweight champion Bermane Stiverne, who pulled out of the fight after learning that Povetkin tested positive for the banned substance ostarine and that the World Boxing Council wouldn’t sanction the fight. Povetkin hurt Duhaupas with two left hooks to the head in round 6 to knock him down and out. The fight was halted by the referee, as Duhaupas was badly hurt from the left hands. The official time of the stoppage was at 2:59 of the 6th round.
