WBC heavyweight champion Tyson Fury has issued a warning to domestic rival Anthony Joshua - giving the British star until Monday to sign a bout agreement for a potential fight on December 3.

The two sides have been negotiating for several weeks - with a contract sent to Joshua and his handlers this past Friday.

“I was optimistic about three weeks ago but it shouldn’t be taking this long to sign a contract. We will know by Monday anyway because if it is not done by Monday then I’m moving on. I’m not waiting around for some guy who has lost three of his last five fights," Fury said.

“He’s lucky that I’m giving him a world title shot but I don’t mind chucking him a bone but I don’t want them to start dictating sh!t to me.”

Fury also fired back at IBF, IBO, WBA, WBO heavyweight champion Oleksandr Usyk, who is coming off back to back decision wins over Joshua.

He tried to face Usyk in an undisputed fight for December, but the Ukrainian boxer is not planning to fight again until early 2023.

However, he claimed Fury was running scared by deciding to pursue a showdown with Joshua, who lost three of his last five bouts.

“We offered them the December 17 date in Saudi Arabia for the undisputed heavyweight championship of the world and everybody wanted that date. Usyk said he was injured and isn’t ready until next year," Fury said.

“And now he’s saying I’m scared of him. The little sh!thouse middleweight. I’ll put my fist right through his face.”
