In 2012, Poland's Mariusz Wach took on Wladimir Klitschko, got pummeled for twelve rounds, and then tested positive for steroids. This series of unfortunate events did not get through to the big man, apparently, as after getting pummeled for eleven rounds by Alexander Povetkin last month, he's reportedly failed another drug test.

Thankfully, Polish is rather amenable to Google Translate.

Andrei Riabiński confirmed in an interview with the agency R -Sport that the anti-doping tests performed in Mariusz Wach ( 31-2 , 17 KOs) after the November fight in Kazan with Alexander Povetkin ( 30-1 , 22 KOs ) gave a positive result. - Yes, it's true , we have received such a notice - said the promoter listed on the first position of the ranking WBC heavyweight Russian. - The fight has not been canceled , Wach will be punished . Powietkin will not remain without a win in that sense nothing happened . The problem would be if this winner was caught on doping , but Sasha is clean.

I believe "canceled" in this case means "nullified;" since Wach lost, this will not affect the official result. The substance in question has not been released.

You'd think a guy would be satisfied with being roughly the size of a barge and packing the kind of chin that breaks new ground on the Mohs hardness scale, but here we are.
