David Haye believes that Deontay Wilder will cause an upset and defeat Tyson Fury to reclaim his heavyweight crown.

The two bitter rivals face off tonight in at the T-Mobile Arena in Las Vegas for a third time, with both the WBC and Ring magazine titles on the line.

The pair recorded their heaviest weights on the scales at last night's weigh in, with champion Fury coming in at 277 lbs and Wilder at 238 lbs.

And Haye, who won the world title both as a cruiserweight and as a heavyweight is adamant that the "Bronze Bomber" will be able to avenge his loss against an "ill-prepared" Tyson Fury this time around.

Speaking on BT Sport after the weigh in, Haye said: "I think Wilder has been completely underestimated. Personally I do not believe Fury's training has gone anywhere near as well it did for the second fight as he does not have the motivation to push his body and train for it.

"You've got yourself Fury, who is ill-prepared, versus Wilder who has had surgery on his arm and is now bigger and stronger than he has ever been before.

"Having seen the weigh in, I think that we are going to get a big upset."

The "Haymaker", was left red-faced in the aftermath of the second Fury-Wilder fight in February 2020, after he had claimed to Fury's father John live on air on BT Sport that his son would crack up and lose to the American.

David Haye himself was close to fighting Fury back in 2014, but had to pull out of the event twice due to injury.
