TYSON FURY is pulling out all the stops in an effort to beat Oleksandr Uysk.
The Gypsy King was handed his first-ever defeat by the Ukrainian maestro in their fight in May.
Usyk's thrilling split-decision points victory saw him crowned as the first undisputed heavyweight for 24 years.
Only three of the belts are on the line this time after Usyk was forced to vacate the IBF strap, which was later won by Daniel Dubois.
But Fury is determined to exact revenge in Riyadh on Saturday night.
And the Morecambe mauler, 36, has made FIVE big changes to his camp to make sure he's the one having his hefty arm listed this time.

Not speaking to Paris during camp
Fury revealed he has not spoken to his wife or kids for months as part of his fight preparation telling : "It’s been a long camp, hasn’t seen my wife and kids in three months.
"I haven’t spoken to [my wife] at all in three months. Not one word, sacrificed a lot. But it’ll all be worth it, 100 per cent."
Paris responded to the comments on social media by saying she fully supports him as it is "what he needs".
The couple got married back in 2008 and have now had seven children together; Venezuela, Prince John James, Prince Tyson II, Valencia Amber, Prince Adonis Amaziah, Athena and Prince Rico.

Ditching dad John from corner
Madcap John Fury had previously been a mainstay in his son's training camps ahead of fights.
He was heavily criticised for his actions following the first fight in May, and has been removed from the camp this time around.
Instead, the Gypsy King will be taking on council exclusively from head trainer SugarHill Steward, Andy Lee and the cutman.
Asked about John's absence from camp, Steward said: "Tyson Fury is just ready right now, along with myself."
Growing a huge beard
Fury was a clean-shaven giant when he took on Usyk the first time.
However, the glimpses we have seen into the camp this time around have seen him with a great big bushy beard, with Fury admitting he has not touched anywhere from the eyeballs down when it comes to grooming.
But that may have to change before fight night, as the board in charge of the rules for the rematch state fighters must have their jawline visible for safety reasons.
And unless he trims his facial hair to suit the rules, Fury could be prevented from fighting altogether. So watch this, or rather that, space.
Putting on even more weight
Fury has piled on the pounds for his rematch with Usyk.
Last time out the 6ft 9" boxer weighed in at 18st 10lbs or 262 lbs.
But Fury revealed to that he was aiming to get up to 21st.
Whether this is simply a bluff or not, nobody knows.
But if he tips the scales at that incredible weight during Friday's weigh-in, it would be heaviest he would ever be in a boxing ring.
Refusing to do open workout
Fury was involved in a bizarre open workout session at Riyadh Plaza earlier this week, as he strangely took longer to travel to the venue by boat than spent in the ring.
Steward laced up his gloves seemingly ready for the open workout session, before Fury bowed to the crowd and took them off again.

He then evaded all of DAZN reporter Claudia Trejos' questions by reiterating that he is going to dish out 'a lot of pain' on Saturday night.
On the so-called workout session, Steward said: "He’s always had like a silly demeanour and [been] playing around, but this is a different side of him."
