Johnny Fisher's father launched a stinging rant at Gareth A Davies after he called out his son's controversial victory over Dave Allen.
Fisher secured a contentious split-decision victory over Allen in their undercard bout on the Oleksandr Usyk vs. Tyson Fury 2 card.
He earned the win despite being dropped in the fifth round, with many boxing fans and critics alike believing Allen had done enough to claim the victory, including journalist Davies and pundit Spencer Oliver.
The talkSPORT duo slammed the verdict of Fisher vs. Allen as they made their feelings clear.

'Big' John Fisher, however, did not appreciate Davies and Oliver's comments.
He was involved in a furious row with Davies and said he 'lost all respect' for him following his criticism.
On iFL TV, John began: "Totally respect anyone's opinion who thought Dave won the fight, but the way you and Spencer went over the top... I thought you were serious journalist... you showed how incapable you are of actually reporting on a proper fight."

John then revealed he watched the fight back, detailing how he scored the heavyweight contest.
"Watched it back. He won round one to four round, won round 10 and round seven you could have called it for Johnny," he explained, before adding: "So, for you to say it was a robbery and disgusting...
"You was welcome in my house before... you'll never be welcome in my house again because you acted like an utter complete disgrace and I'll tell you to your face because I'm a man. I'm not holding back.
"Anyone can say they think Dave won the fight... Dave's team themselves said it wasn't a robbery and you're shouting out things like that."

Saudi boxing chief Turki Alalshikh also disagreed with the Fisher vs. Allen decision as he released a statement in the wake of the Riyadh card.
On X, he wrote: "The fight between Fisher and Allen I counted differently and it’s my own opinion shouldn’t be considered as judgment."
Following the controversy, a rematch between Fisher and Allen has been mooted.
