WBO/IBO/WBA/IBF champion Wladimir Klitschko (60-3, 51 KOs) is ready to move forward, without Alexander Povetkin (26-0, 18 KOs), if the two sides are unable to reach an agreement by the WBA's deadline date of June 7th. The fight is scheduled for October 5th in Moscow, Russia.

There is a still a dispute over which organization will be used to test both boxers for performance enhancing drugs. Klitschko wants to use NADA [Nationale Anti Doping Agentur], based in Germany - while Povetkin's side wants to use RUSADA [Russian Anti-Doping Agency], which the Klitschko side rejected. Both NADA and RUSADA are affiliated with WADA [World Anti-Doping Agency]. There are other outstanding issues that need to be resolved .

"The contract has not yet been signed. There are still a lot of points remaining [in the contract] and because of that we can not move forward [with the fight]. At this point there are still too many questions that have no answers from the team of Alexander Povetkin. From our side, all of the answers have been provided in connection to the contract. There is a good verbal communication, but when it comes to the legal side those issues are there. I hope we get beyond this stage, and the contract is signed. If we don't sign it, then we will move on without Povetkin," Wladimir told Reklama.
