Jake Paul has publicly blasted the Fury family for their handling of the cancelled fight with Tommy Fury, whilst calling father John Fury a 'weirdo'.
It was announced on Monday that Fury would be pulling out of the fight after suffering a broken rib whilst also struggling with a bacterial chest infection.
The Manchester-born fighter has said that his camp had not gone to plan from early on and struggled throughout the last four weeks.
Paul will still fight on December 18, facing Tyron Woodley in a rematch having won their first meeting in August via a split decision.
And Paul had some few choice words for the Fury family when speaking to former NFL star Pat McAfee on YouTube.
He said: "They’re a sketchy bunch of people all around. I mean, look at John Fury. The guy is a weirdo. He spent 11 years in prison.”
Paul's comment on John come after the two had an explosive argument live on BT Sport during last month's pre-fight press conference.
BT released an apology after both men used foul language on multiple occasions.
After being made aware that Fury would pull out of the fight, Paul said he was frustrated by the news.
Paul added: "I am pretty sad. You get your mind set on an opponent – all the personal s*** that lead up to it… it was personal. I wanted to take him out. It sucks.
“The Fury’s have a history of pulling out of fights – Tyson Fury has pulled out of five fights. But the show must go on.”
Woodley fought a close eight-round fight with Paul back in August, with the latter being declared the winner on a points decision.
Paul revealed to McAfee that Woodley was his first choice replacementafter becoming aware of Fury's decision.
He said: "He was the first name. My manager hit him up and he wanted to do this. He has been in training and is in shape.
“I have got so much better in this camp and I want to show people I didn’t perform at my best in the last fight – I want to get that knockout.”
