Former unified light heavyweight world champion Sergey "Krusher" Kovalev (30-2-1, 26 KOs) is training hard for his scheduled fight with Vyacheslav "Lion-Heart Chingonskyy" Shabranskyy (19-1, 16 KOs), which takes place on Saturday, November 25 at The Theater at Madison Square Garden.

There were numerous questions rumors regarding Kovalev's new trainer, and the Russian boxer finally decided to reveal his new coach.

Kovalev said he is now being trained by experienced coach, Abror Tursunpulatov, who help develop several top amateurs - including Uzbek boxer Fazliddin Gaibnazarov, who captured a gold medal in the 2016 Rio Olympic games.

Kovalev is very pleased with his decision.

"There is a general understanding of what we have to do and how to prepare, and this is the main thing. I hope that our new working relationship will bring new success in my career as a boxer," said Kovalev, 34 years old.

Kovalev is trying to bounce back in his career, after suffering back to back defeats to Andre Ward. He lost a close twelve round decision to Ward last November, and then he was stopped by Ward in their June rematch.

After the second fight with Ward, he had a bad falling out with longtime trainer John David Jackson.

Even before the rematch with Ward had taken place, there was friction between Kovalev and Jackson - including a situation first reported on BoxingScene.com, where Jackson actually held discussions with Ward's team on the subject of jumping ship.

After they split, there were all sorts of rumors regarding Kovalev's next trainer - and several names were being kicked around like Virgil Hunter, Freddie Roach and Robert Garcia.

But there was also talk that Kovalev felt more comfortable with an Eastern European trainer.

Tursunpulatov believes he can help Kovalev in a lot of areas to sharpen his tools.

"I've known Kovalev for a long time. A year ago, after the Olympic Games in Rio de Janeiro, I came to America with my student, who is also a professional boxer. Here we got to know Sergey more closely, and since then we are actually one team. I could not refuse his request to work with him," Tursunpulatov said. "I like Kovalev as a person, we have excellent mutual understanding."
