In December 2011, a deal was reached for Povetkin to make his second defence against then WBO cruiserweight champion Marco Huck (34-1, 25KOs) on 25 February 2012 at Porsche Arena in Stuttgart, Baden-Württemberg. Huck made the challenge in the post fight press conference of Povetkin's win over Boswell. It was noted that Huck would not vacate his WBO title, until after the fight, where he would assess the situation. Huck stated if he was to win the title, he would likely remain at heavyweight to challenge one of the Klitschko brothers, but would be given 10 days by the WBO to decide. Huck reached out to David Haye and Evander Holyfield to help with sparring. In January 2012, the promoters of Huck, Povetkin and Rahman attended a meeting where they discussed the winner of Povetkin vs. Huck would defend the WBA title against Rahman next. During this time, trainer Teddy Atlas failed to travel to Russia and announced he had parted ways with Povetkin. Russian trainer Alexander Zimin stepped in on short notice. For his debut at heavyweight, Huck weighed 209.4 pounds and Povetkin weighed 229.2 pounds.
