A potential cruiserweight blockbuster between Tony Bellew and Oleksandr Usyk is inching a few steps closer.

Eddie Hearn, promoter for Bellew, has two positive face to face meetings with Alexander Krassyuk from K2, who promotes Usyk.

"I had a very positive meeting in Paris yesterday and again today with Alexander Krassyuk from K2," Hearn told Sky Sports.

Last month, Usyk unified the entire weight division with a dominating performance over undefeated Murat Gassiev to unify the WBC, WBO, WBA, IBF cruiserweight titles in Moscow, Russia. The win also saw Usyk as the overall winner of the World Boxing Super Series tournament.

After that victory, Usyk specifically called out Bellew - and the Olympic gold medal winner is willing to take the fight at cruiser or heavyweight.

Usyk views Bellew is a necessary step on pace to getting a future crack at IBF, IBO, WBA, WBO champion Anthony Joshua, who is also promoted by Hearn.

Bellew was the WBC champion at cruiserweight, but dropped the belt to make a move to heavyweight in March 2017 - for a lucrative fight with David Haye. Bellew stopped Haye in eleven rounds, and then stopped him five vicious rounds when they fought again in their May 2018 rematch at the O2 Arena in London.

Bellew, who in the past was looking for a world title fight at heavyweight, is now willing to drop back to cruiserweight - if he gets a crack at Usyk with all of the world titles at stake. 

Hearn is hoping to finalize he fight in the coming weeks.

"It's not done, but we made some good progress and will continue those discussions over the next few days. Both fighters want the fight and I'm hopeful we can get it done," Hearn said.

"It's a brutal, brutal fight, but Tony is ready to roll the dice to become undisputed champion."
