The promoter previously revealed that the former heavyweight world champion would box again before taking on Anthony Joshua in their long-awaited fight later this year and has confirmed that an announcement is imminent.
Warren told Sky Sports: "We'll hopefully be in a position to announce it next week, that's what we're looking to do.
"So keep watching this space, and it'll be a good opponent - it'll be good for him. He can't afford to slip up, because obviously AJ's got his fight in a few weeks' time.
"[Joshua's] got to come through that, Tyson has to come through his, and then the big one will be in November."
Joshua will take on Kristian Prenga in a tune-up fight in July and his promoter Eddie Hearn says that plans for the all-British bout could be scuppered if either fighter loses their warm-up clash.
The Matchroom chief told Sky Sports: "In my opinion if either fighter loses, you cannot do the fight.
"I will feel sick at the ringwalk on July 25. Especially with what AJ's come back from. I mean there is that worry. Will he be the same? Everything we see in camp and in sparring lends us to suggest yes. But there's a lot to overcome. That's the importance of this fight as well in July."
Hearn added: "Now we have signed to fight Tyson Fury. He has signed to fight Anthony Joshua. The only thing that stands in the way is July 25."
Meanwhile, Warren confirmed that a new opponent will also be unveiled for rising British heavyweight star Moses Itauma -who is closing in on a world title shot.
The promoter said: "He's fighting a top 10 heavyweight, we expect to get the fight we want to make over the line. Again, a great heavyweight fight.
"This division is on fire."
