Povetkin knocks out Duhaupas in 6.

WBC number 1 ranked heavyweight (for the time being) Alexander Povetkin (31-1, 23 KOs) scored a sensational sixth round Knockout over replacement opponent, the current WBC silver belt holder Johann Duhaupas (34-4, 21 KOs) at the Ekaterinburg Expo Center in Ekaterinburg, Russia. Povetkin completely outclassed the more predictable Duhaupas throughout the first 3 sessions, punching in flurries, taking an early lead..  Approaching the end of the fourth Povetkin hurt Duhaupas with a fast combination of shots, which looked to signify the Frenchmans fate..  6 minutes later, close to the end of the sixth, Povetkin landed a terrific left hook, knocking Duhaupas out cold just seconds before round ended..
The time was 2:59.
Duhaupas saved the show, by stepping in, following the series of events due to Povetkin failing a drug test and the WBC withdrawing their sanctions as a result.
