Tyson Fury's uncle and trainer has told Sky Sports News that they are angry with the way David Haye's camp have behaved after their fight was postponed for a second time.
Peter Fury claims the former heavyweight champion has wasted the last year of his nephew's career and they haven't even had the courtesy to apologize.
Haye cancelled their re-arranged February clash after undergoing shoulder reconstruction surgery which could see him retire for a second time.
"It has stalled Tyson's career by a year," said Fury senior. "We're behind a year and we've lost some serious ranking points as well.
"We lost a mandatory for the IBF with Pulev, that all got put to one side, so to say the least we've got an ill feeling towards what has happened.
"We're going to move on," added Fury sr, "David Haye's credentials as a fighter has never been in question; he's a world class fighter. As a human being and as a fighter in boxing we wish him all the best.
"But as with the conduct with his camp and business dealings that's another matter entirely. We're not going to do any business with that camp ever again regardless.
"His camp has not even offered, not even said sorry, they've not said anything. We've not even got an apology from that side, never mind anything else, so we'll just do our own thing and see what happens.
"This is boxing; we're not going to hold grudges or whatever. They are finished, there is a line drawn underneath them and a line drawn underneath them in the future.
"He's never going to step in the ring with Tyson or none of their camp is, so we're going to move on and hopefully to better and greener pastures."
