Tyson Fury is expected to fly out to Las Vegas to help his half-brother Tommy prepare for his fight with Jake Paul, according to his father John.
After a series of back-and-forth insults that first began on social media, the pair are now set to meet in the ring on 18 December in Tampa Bay, Florida.
Tommy has already flown out to the States to begin his preparation, and will soon be joined by Tyson, who will also play a pivotal role on fight night.
John Fury told BT Sport: "Tyson's going to be in his corner that night. I think Tyson's flying out there in a few weeks to help him out.
"Whatever desire he's missing, Tyson will put there, I'm sure of that.
"Tyson will sort his head out so I'm looking for a Tommy win in explosive fashion - the end of Jake Paul."
Tyson, who is fresh off one of the great heavyweight fights of all time, in which he defeated Deontay Wilder for a second time to retain his heavyweight crown, has issued a stark warning to his younger brother.
The Gypsy King said that if Tommy is unable to defeat Paul, he would have to change his surname.
Tyson told Behind The Gloves: "If Tommy can't splatter Jake Paul, I'll retire him from boxing myself.
"He's got ambitions of being a world champion, never mind beating some YouTube guy.
"His name's Fury. If he can't beat Jake Paul, I'll have to change his name."
Paul's emergence in the boxing world has been a major point of controversy among fighters and pundits alike.
However, out of his four professional fights, Paul is yet to taste defeat - though the calibre of his opponents has been regularly questioned.
So far, he's beaten fellow YouTuber AnEsonGib, retired basketball player Nate Robinson and two former MMA stars in Ben Askren and Tyron Woodley.
Paul has also made no secret of his desire of setting up what would be an incredibly lucrative meeting with UFC star Conor McGregor at some point in the future.
Tommy also boasts a perfect record to date. His latest victory came via unanimous decision against American Anthony Taylor.
