The petrifying state of Ukraine and its residents is no secret.

It has impacted everyone in one or the other way, and even someone like boxing heavyweight champion Oleksandr Usyk is no exception to that.

As has been revealed by his wife Kateryna in an interview with PravdaTUT, he lost a staggering 10KG just a week after Russia declared war on the nation.

“Sasha lost 10 kilograms in a week of the war. He was so horrified, in such shock, he was so torn apart… He saw what I was doing,” she said.

"I said: 'Sasha, please, people are asking, you need to speak, somehow support'. It is very difficult for him. At first he digested it inside.

"Well, firstly, let’s be honest, we have never been in such a situation before. Our entire generation could never have imagined this. And here it is, a shock.

"To be honest, he doesn’t really like giving interviews in normal, peacetime anyway. Now it’s difficult for him, of course, but he still goes on the air, says something.

"His position is clear. He has always been for Ukraine, he has always glorified it and will glorify it for as long as he has enough health and strength.

"Now he understands how important for him, let’s say, even the next fight. For him, every fight is important, but now, when blood is shed in your country, you want to glorify Ukraine, you want to be proud of it.

"I’m just so proud that I’m from Ukraine, that I’m Ukrainian! Thank God that this happened.”

None of the current shambles, though, have affected the champion in Usyk, who served in the Ukrainian army, reflecting once again the kind of fighter he is.

He recently left his home country, however, to prepare for his upcoming bout with Anthony Joshua, which, as you can expect, will be about more than just a heavyweight title.
