Tyson Fury and Wladimir Klitschko are close to selling out the 55,000 seat ESPIRIT Arena in Dusseldorf, Germany.
Mick Hennessy, Fury's promoter, says that the fight has already sold close to 40,000 tickets and is on course to be a sellout.
"We're already close to selling 40,000 tickets and it is guaranteed to be a 55,000 sell-out." he said to The Mirror. "It's selling brilliantly and worldwide this fight could be worth more than 30 million.
Fury had talked about moving his camp to Castlebar in Mayo, but Hennessy says he is staying in England.
"Tyson isn't going to Ireland now. His camp is going so well here he has decided to stay. He has been alternating his training camp between Bolton and the Lake District and he and Peter see no reason to change things."
