World heavyweight champion Tyson Fury says fight fans can expect some 'massive news' about his next bout soon.
And the 27-year-old has hinted that he will be squaring off against a surprise opponent.
Fury captured the WBA, WBO and IBF titles (but was subsequently stripped of the IBF belt) when he out-pointed Wladimir Klitschko in Dusseldorf last November.
And it was subsequently announced that the pair would square off again this year, Klitschko having exercised a rematch clause in his contract.
However, Fury tweeted on Saturday evening: "Some massive news coming soon, had to come to London for an urgent meeting about a massive fight, TBA very soon, u will not believe who!!!!!!"
He has recently revealed he might not even box again and is still waiting to find out when and where the rematch with Klitschko will take place, so his meeting in London could well clear that up.
It is hard to try and guess who else Fury will fight other than Klitschko.
The WBC world champion Deontay Wilder has said he wants to fight him in the UK but looks set to face mandatory challenger Alexander Povetkin first, while Anthony Joshua's promoter Eddie Hearn has been in talks with IBF holder Charles Martin's team about an April 9 clash at The O2, London.
Former WBA heavyweight champion David Haye will fight again in May but has pulled out of two proposed fights due to injury in the past, and Fury has said they will never meet in the ring.
Current WBA World champion Ruslan Chagaev is fighting challenger Lucas Brown in Grozny, Russia on March 5, while interim champion Luis Ortiz is taking on Tony Thompson in Washington, America, on the same night.
Fury has admitted belts are not important to him after replacing Klitschko as the world's No 1 but New Zealand's Joseph Parker is ranked second behind him by the WBO and fought three weeks ago, knocking out Jason Bergman to move 18-0-KO16.
