The possibility of a rematch between Joshua and Usyk has gained traction recently after the Ukrainian received permission to leave his country and prepare.
It was speculated that he would stay and continue to defend his country, but he has now confirmed that he has left Ukraine.
Promoter Eddie Hearn confirmed that the fight will go ahead, and has said that Joshua is ‘chomping at the bit’ to avenge his loss in their previous fight.
Hearn keeps in close contact with Usyk’s promoter as the ever-evolving situation in Ukraine could change proceedings.
In a recent interview, Bellew shut down any questions regarding the heavyweight battle by saying: “I don’t want to talk about it.
“I think what Oleksandr Uysk is going through is horrendous, it’s a disgrace and I don’t want to talk about it to be honest with you.”
Bellew did take time to express his admiration for the Ukrainian, however, stating: “Oleksandr Usyk, what a man, what a person. It’s unbelievable what he is doing.
“It’s mad, we shouldn’t even be talking about sport when it comes to what’s going on in Ukraine right now, but we have too.
“Until I see Usyk leave Ukraine safely and get out of there, I don’t want to talk about it.
“You can’t talk about a fight that is happening when the man is out there fighting a f****** war. You just can’t talk about it.”
At the start of March, Usyk joined the Kyiv’s resistance force. At that time, he wasn’t sure about what his future would be like in boxing.
His brave commitment to stay and defend his country was followed by fellow world champion Vasyl Lomachenko.
Usyk said: “I really don’t know when I will be stepping back into the ring.
“My country and honour are more important to be than some championship belt.”
In the past week, both boxers were offered the opportunity to resume their boxing careers.
