The mandatory challenger for the WBO cruiserweight title Denis Lebedev, and champion Marco Huck have signed an unprecedented contract for their fight on December 18 in Berlin. Lebedev's manager, Vladimir Hryunov, has informed Alexander Pavlov that both boxers have agreed to take part in doping tests under the rules of WADA [World Anti-Doping Agency]. 

Hryunov is also the manager of undefeated Olympic heavyweight Alexander Povetkin. If you remember, Hryunov and Povetkin were pushing champion Wladimir Klitschko to submit himself to doping tests when the two parties were negotiating for a fight a few months ago.
