Less than a week removed from his biggest career win to date, Bermane Stiverne has been delivered his most promising news as a professional prizefighter.

Negotiations are officially underway for the once beaten heavyweight contender to next face Vitali Klitschko for a heavyweight title. The WBC notified both camps that Stiverne is now the official mandatory challenger, thanks to his HBO-televised 12-round rout over Chris Arreola on the road last weekend in Ontario, California.

The two sides will have 30-days to work out an agreement, or else the proposed bout will head to a purse bid on June 3 at the WBC headquarters in Mexico City.

"We are quite pleased to receive this letter as it represents an important step in the right direction towards our ultimate goal which is the WBC heavyweight championship," said Camille Estephan, Stiverne's manager's. "This is an opportunity to rewrite history in getting the most prestigious title in the sport. Not only is it the most prestigious in the sport of boxing it is one of the most prestigious in the world of sports generally all sports confounded.

"We are very pleased with Bermane's spectacular victory in the eliminator against Chris Arreola yet not satisfied. We will only be satisfied when we achieve our ultimate goal which is bringing the belt back to North America from one of the best heavyweights of all time Vitali Klitschko."

There was concern about the elder Klitschko returning to the ring. A suggested retirement was revealed following his 4th round stoppage of Manuel Charr last September. Klitschko's main focus immediately thereafter was to contend for  a spot within the Ukraine Parliament. Rules in his native Ukraine forbid any member of its parliament to simultaneously hold a separate profession.

However, the long time top heavyweight gave his word that he will return to the ring and that Stiverne is next in line.

"There is an official contender - Bermane Stiverne. The fight will take place, we only have to set the date," Klitschko said earlier in the week.
