WLADIMIR KLITSCHKO is keeping himself fighting fit as negotiations for his rematch with Tyson Fury continue.

Rumours have swirled about the rematch – which was written into the contracts of their first fight – not happening at all, however the former heavyweight champion took to social media to provide a brief update.

“Rematch vs Tyson Fury still in the making. I will keep you posted. Meanwhile [I’m] staying in shape,” he said.

It was even suggested Klitschko may elect to box at Rio 2016, should professional fighters be allowed to enter the Olympic Games. Wladimir won gold at Atlanta 1996, and while he admits he would be interested in representing Ukraine again, only has one objective in mind for now.

“I have always said that I would love to participate again in the Olympic Games, but right now I’m only focusing on my rematch with Tyson Fury,” he said.

Fury’s promoter, Mick Hennessy, recently spoke to Boxing News about talks over the rematch, mentioning that it is likely to happen in May or June, with several venues in play.

Marrying up a date between potential broadcasters and venues seems to be the main sticking point at this stage, as an official announcement is awaited.
