Wladimir Klitschko (64-5, 53 KOs), the former WBO, WBA, IBO, IBF heavyweight champion, is refusing to rule out the idea of a potential return to the ring.
Klitschko, 42-years-old, ruled the weight division for over ten years - until he suffered a shocking twelve round decision loss to Tyson Fury in November 2015 in Germany.
He was inactive until April of 2017 - when he collided with Anthony Joshua in an IBF, IBO, WBA unification before a crowd of 90,000 fans at Wembley in London.
He had Joshua down in the sixth and was a few punches away from a win, but the British superstar survived - and came back down the stretch to score a stoppage of Klitschko in the eleventh round.
Klitschko executed the rematch clause and it was being put together for the fall of the same year.
Those plans were quickly cast aside when Klitschko announced his retirement from the sport.
Now with over a year of inactivity, Klitschko - under the right circumstances - would consider fighting again.
"You never say never, things can change," Klitschko told 112 International. "People often switch careers during their lifetimes.
"Look at Arnold Schwarzenegger: he was an athlete, then an actor, then a politician, than a businessman, and now he's involved in taking care of the planet.
"Maybe if I feel the time is right to help a certain charity, I'll get back in the ring."
And when he was pressed further on the matter, Klitschko gave a diplomatic answer.
"I had great times in the 27 years I spent in the sport," Klitschko said. "I learned a lot and I traveled a lot, which was my goal when I first started boxing.
"I have achieved what I never dreamed of; I've done and experienced things that I had never even thought about. I've learned that when some doors close, others open. It's all life experience and sport really is amazing."
