Tyson Fury believes his dad John would knock out Eddie Hearn in one round if the pair fought on his undercard.
After his father posted a picture of his body transformation last month, Fury joked he could appear on the undercard of his world title fight against Dillian Whyte in April.
Fifty-seven-year-old John retired from boxing over 25 years ago after suffering consecutive knockout losses and finishing his career with a record of 8-4-1.
And his son has doubled down on his plan to put John on his undercard by joking his promoter Frank Warren is working hard on getting a deal done.
"I'm trying to get John on the undercard to be honest, we're still working on that. Frank's working very hard behind the scenes, it's not been announced so don't be surprised," he told Queensbury Promotions.
And when asked if John could fight Eddie Hearn, Fury replied with a brutal putdown of the Matchroom Boxing boss.
"Me dad will chin Eddie Hearn in one round, it won't [go] 30 seconds," he added.
Fury's fight with Whyte will mark his first in the UK since 2018, with his last five fights taking place Stateside after signing a $100million deal with Top Rank in 2019.
John has been unable to attend any of his son's fights in the US because of a grievous bodily harm charge dating back to 2011.
Fury also seemed keen at the idea of booking his brother Shane on the undercard against Whyte's brother Dean after the pair have traded words in the past.
Both Fury and Whyte will get career-high paydays for their world title clash, with Fury earning £31million and Whyte taking home £6m.
Fury also thinks Whyte's recent silence on social media has come from a warning he sent to his rival to stop badmouthing him.

"I did tell him on Instagram a few months ago, every time you call me a bad name your percentage will go down. He didn't call me many bad names after that," Fury added.
"That's why he went quiet. He did go quiet when I did tell him that, I think 20 per cent for him is more than fair. He could get a possible [£10million] if he beats me.
"That there compared to his last fight when he got £250,000, that's a lot of money. That's seven times more than I got to fight Wladimir Klitschko.
"I was like ten times bigger than he was on that stage, so he's got to be very very thankful to me. If I was him I'd be sending me gifts and stuff through the post."
