Heavyweight contender Dillian Whyte is not concerned with Derek Chisora's recent threat of traveling over to Russia to help prepare Alexander Povetkin.

Povetkin and Whyte were scheduled to collide this month, but their fight was pushed back due to the coronavirus pandemic. There is a tentative date in July, which is likely not going to happen as planned. The new date may come down in late July or early August.

Chisora has already spoken with Povetkin about flying over to Russia to help him prepare for Whyte.

"I've already said to Povetkin that, if he needs me, I'll come and help him. I'll fly to Russia," Chisora told The Boxing Show on Sky Sports.

"He said that he'd get me a private jet to come. Povetkin is my boy. I don't care [what Whyte has to say]. The Russian has already spoken to me and said: 'When it's time I'll send a plane to pick you up and you can help me train'. I'm down for that."

Chisora believes he was robbed of a win when he lost a twelve round split decision to Whyte in December 2016. In their 2018 rematch, Chisora was up on points when he was knocked out in the eleventh round.

Whyte believes Chisora is simply talking smack to secure himself a trilogy bout.

If Chisora is able to defeat his upcoming opponent, Oleksandr Usyk, then Whyte has promised to hand him another brutal knockout.

"It's Derek being Derek. He's good at talking his way into an ass-whooping. The first time he said it was close. The second time I cleaned his clock. The knockout I gave him was one of the worst you will see in boxing," Whyte told Sky Sports.

"I ain't got no beef with Derek. I'm cool with the guy but clearly he has a vendetta. Derek is a stepping stone and I've stepped over him twice already. If he wants to be brutally knocked out again I'll take some easy money! If he beats Oleksandr Usyk and there's a belt on the line, I'd gladly take the belt off of him."
