The Gypsy King' announced his retirement after beating Dillian Whyte, but he has unsurprisingly gone back on that.
With fights against Oleksandr Usyk or Anthony Joshua unable to be made, Fury has opted to face fellow Brit Chisora for the third time.
Their trilogy takes place at The Tottenham Hotspur Stadium.
Speaking on Thursday, Warren - Fury's promoter - suggested that the WBC world heavyweight champion is planning to fight Usyk and Joe Joyce next year.
"That fell apart and then we had to go down the ratings," Warren explained live on talkSport.
"Derek was available and that's who he's fighting now. He's the highest available contender.
"If Tyson comes through Dec 3, he's gonna fight Oleksandr Usyk and after that, he may wind up fighting Joe Joyce.
"It's not our fault or Tyson's fault [the Joshua] fight did not happen, it's not our fault, 100 per cent."
When asked if he thought Fury vs Joshua would ever happen, Warren answered: "No.
"AJ's gonna come back - a couple of fights to get him back into the situation, he's gotta win those fights. I think he's very vulnerable.
"I'm not being disrespectful to him, but I wouldn't be surprised by any fight that he loses now because I just think he's a very beatable fighter now."
Usyk beat Joshua in their rematch in August in comprehensive fashion. The Ukrainian has since returned home and he does not intend to fight until early next year.
After hearing this, Fury subsequently offered AJ a chance to contend for his WBC title.
Progress looked to have been made between the two parties, but this fell apart after they reached an impasse.
Fury and AJ are now going their separate ways and will take underwhelming fights. Joshua is also set to return in December, but his opponent is currently unclear.
The champion meanwhile has already beaten Chisora twice and it is tough to justify this fight taking place.
As for Warren saying that Chisora is the "highest available contender" in terms of rankings, that is simply not true.
Joyce is a much tougher adversary and he had stated that he would have stepped in to fight in December after stopping Joseph Parker in September.
Fury vs Joyce would be a much better fight, but boxing fans will have to wait until late next year to see it, provided the Gypsy King does not retire, again.
