"At the start of the year, all parties involved in the fight - fighters, promoters, managers - all signed a contract as to how the negotiations would take place," said Warren.
"In that agreement there was a clause that made it very clear there was an arbitration situation going on as far as Tyson is concerned - so everyone was aware of it and that we were awaiting the outcome of that.
"There was another clause in there regarding confidentiality and that we would make announcements together, so that we would all be on the same page.
"Within a very short space of time, Eddie Hearn breached that agreement by making announcements.
"Every week there was something, announcements about announcements, the fight is done and so forth.
"That was totally untrue. The fight wasn't done, it wasn't signed and every time I did an interview I just said the truth.
"All these announcements, that were being made on a regular basis by Hearn, I don't think helped and caused a lot of confusion."
