Frank Warren, co-promoter for WBC heavyweight champion Tyson Fury, is not happy that Eddie Hearn, promoter for IBF/IBO/WBA/WBO champion Anthony Joshua, provided confirmation to the media that a two-fight agreement was signed and sealed between their boxers.

On Monday, Hearn revealed to ESPN that both Joshua and Fury had signed the two-fight agreement - with both sides now working to finalize the date and location for the first encounter.

The first meeting is being targeted for June or July, with the rematch taking place in the fall.

Both sides are motivated to ensure both fights take place in 2021.

According to Warren, neither side was supposed to say anything unless a joint announcement was made.

“Everybody signed an agreement that there would be no announcements unless they were joint announcements and that came out the blue yesterday," Warren explained to Talk Sport.

“We are all not happy but it is out there now – there is nothing we can do about that. But there is a long way to go yet in as much we have to sort out venues. We have a couple venues we are looking at and that is where we are.

“I believe it will happen when they get in the ring. We’ve still got a way to go. But everybody is on the same page to make this work. We are all collectively working to get a venue sorted now. It is the biggest fight ever in British boxing, bar none.

“Two guys who hold all versions of the world title between them, both Brits, and it don’t get no better than that. It is massive. Nothing compares to it. I have been involved in some big fights over the years but they pale in comparison to how enormous this fight is. And in world boxing, it is the same. When you speak to anybody, all they talk about is when the fight is going to be on. Hopefully it is going to happen now and everyone’s wish is going to come true.”
