Hughie Fury raged against the judges’ decision in defeat when he was said to have lost to Joseph Parker.
Fury came up short in his attempt to emulate cousin Tyson by claiming the WBO heavyweight title at Manchester Arena.
A stunned Fury could not believe the judges’ decision as Tyson raged to the officials at ringside.
Fury, who suffered his first loss in 21 pro fights, said: “I don’t think Parker won the fight. The scoring was way off. I thought I was landing. The judges have scored it and I don’t know what happened.”
Fury, 23, added: “I thought I was ahead on the scorecards and I don’t understand. I thought I won.”
He drew on one card 114-114, while the other two judges scored the fight 118-110, which appeared harsh on the challenger.
But Fury simply did not land enough shots as he tried to copy Tyson’s tactics against Wladimir Klitschko by hitting on the outside.
Instead, Parker took the fight to Fury in every round and landed the cleaner shots as he stretched his unbeaten record to 24-0.
Fury’s tactics were to use his superior reach to hit and run. Parker had vowed to hunt Fury down and caught him early in the first round before the challenger recovered to land a couple of jabs.
That set the tone for the fight as Parker dominated the centre of the ring and Fury tried to pick him off as he came forward.
Fury landed a right hand in the fourth before he suffered a nasty cut over his right eye from what looked like an accidental clash of heads.
Fury’s rugged training camp in the Lake District was like the setting for Rambo – but first blood went to the Kiwi.
Fury landed a big right at the start of the sixth, but Parker didn’t flinch a muscle. Fury also connected with a right uppercut and that round was his.
Still Parker came after Fury, who scuttled around by the ropes, and pinned him in a corner with a left-right combination.
It was far from being a classic as Fury was content to remain at range and attempt to pick Parker off. Fury caught Parker at the start of the ninth, but it just provoked the champ to unload on him and briefly the challenger looked stunned.
Fury hit back before Parker charged him and, for a few furious seconds, we had a contest worthy of a world title.
It didn’t last, though, and too many of Fury’s jabs were falling short.
Parker finished strongly and hurt Fury at the start of the 12th round with a clean shot right on the button.
Fury’s corner celebrated like they had won at the final bell and the challenger was embraced by in the ring by an overweight Tyson.
But the judges scored the fight in Parker’s favour to put him in the mix for a unification clash with WBA and IBF champ Anthony Joshua.
