LONDON -- WBC world heavyweight champion Tyson Fury said Saturday that he plans to fight in London on Dec. 5, but his opponent is unknown.

"I'd just like to announce I'm definitely fighting December the 5th in London. Opponent to be announced very, very soon," Fury said in a video message posted on his social media accounts. "Just working on some opponents. Let you all know who it's going to be shortly."

Fury and his co-promoter Frank Warren recently expressed doubt that a third fight with American Deontay Wilder would happen in 2020.

Fury claimed the WBC belt off Wilder with a seventh-round stoppage in February, after their draw in 2018.

A fight between undefeated Michael Conlan and former WBO junior featherweight champion Isaac Dogboe has been agreed upon for Dec. 5 at Royal Albert Hall in London. That fight is expected to be part of the Fury card, sources told ESPN's Steve Kim.

Fury, 32, announced in June that he had agreed to a two-fight deal with Anthony Joshua. The sides said that the first bout could take place in 2021 in what would be an all-British showdown between the current holders of the heavyweight belts.

Joshua is scheduled to fight Kubrat Pulev on Dec. 12 at the O2 Arena in London. The fight was postponed from June because of the coronavirus pandemic.
