Tyson Fury will bring in heavyweights Jared Anderson, Martin Bakole and David Adeleye to help him prepare for his world title clash against Dillian Whyte.
World champion Fury and mandatory challenger Whyte will fight on April 23 at Wembley Stadium.
The grudge fight between the two rivals was made official earlier this week when Whyte signed his contract just hours before the deadline.
Fury has started his trademark social media blackout ahead of the fight whilst Whyte has been preparing in Portugal since the bout was announced last month.
The domestic rivals are no stranger to each other and have previously sparred in the past, with Whyte claiming to have dropped Fury in the lead up to his 2012 fight with Martin Rogan.
And of his sparring partners, Fury said: "I’ll bring in Jared Anderson from the US for sparring, I'll use David Adeleye.
"I’m also going to use Martin Bakole. Bakole is AJ’s mate but I’ve seen interviews where he said he’s sparred us all and I am the only one he cannot land a glove on."
Undefeated heavyweight Anderson, the first of Fury's three sparring partners, won back-to-back National Championships in 2017 and 2018 before turning professional the following year.
'Big Baby' won seven fights in just over a year and would go on to stop Vladimir Tereshkin on the undercard of Fury's trilogy with Deontay Wilder to win the junior NABF heavyweight title.
Anderson served as a main sparring partner for Fury's rematch and third encounter with Wilder and the Brit has previously labelled him as a future champion.
"Tyson said the next heavyweight champion after him is Jared Anderson," Fury's promoter Bob Arum told Sky Sports.
"I saw it with my own eyes how Jared gave him fantastic sparring on both [second and third] of the Wilder fights."
Fury's father John has also sung his praise for Anderson but said the 21-year-old still has "a bit to do" before he establishes himself as a world title challenger.
Can Dillian Whyte hand Tyson Fury the first loss of his career? Let us know your thoughts in the comments section below
Bakole is the younger brother of WBC middleweight titleholder Ilunga Makabu and has 18 professional fights under his belt.
The 28-year-old is unbeaten in his last six fights and has competed against veteran heavyweights Mariusz Wach and Kevin Johnson.
Bakole's only professional loss came against former cruiserweight world titleholder Michael Hunter in 2018, being knocked out in the last minute of their fight.
Adeleye is the least experienced of Fury's three main sparring partners and has just eight professional fights to his name
25-year-old Adeleye balanced his successful amateur career in 2018 whilst studying business management at university.
After graduating, he was signed by Frank Warren's Queensbury Promotions in 2019 and made his professional debut on the undercard of an event featuring Daniel Dubois.
Adeleye won his debut by first round stoppage and has since improved to 8-0, with all but one of his wins coming by knockout.
