Former boxer Wladimir Klitschko had planned a return to the ring, but it was set aside after Russia invaded his home country of Ukraine.
Klitschko is now 46 and, had he returned, it would have been with the aim of becoming the oldest heavyweight champion ever.
He retired in 2017 after losing an incredible 11-round fight against Anthony Joshua at Wembley Stadium.
Who did Klitschko want to fight?
Whilst talking to Piers Morgan on TalkTV, Klitschko admitted that he had been considering calling Tyson Fury out for a rematch after the Englishman beat him back in 2015.
“I was thinking I should tweet Tyson Fury – ‘Last dance?'” he told the TV show.
“Since he wants to retire and we were supposed to have this rematch.”
The Ukrainian then added that his mind is in a totally different place since Russian president Vladimir Putin ordered the invasion of Ukraine.
“I didn’t do it because my mind was now in a totally different world,” Klitschko stated.
He signed up for the Ukraine reserve army in February and has admitted that he is ready to die while defending his nation.
“I asked myself this question when Russian forces in the outskirt of the city. If I wouldn’t be ready for it, I would have left. The city of Kyiv with almost five million, it’s a big city and a busy city, was empty,” Klitschko explained.
“You could hear the explosions constantly, explosions because the fights were going on in the outskirts of the city and you must [consider this question] while you’re in Kyiv or Ukraine.”
