Bob Arum has revealed Tyson Fury is set to make 'changes' for his rematch with Oleksandr Usyk later this year.
The 35-year-old had been unbeaten prior to the clash at the Kingdom Arena in Saudi Arabia but ended up losing on points after being wobbled in the ninth round of the fight.
Fury, speaking recently, made it clear he was eager to bounce back - with the pair set to do battle again on December 21.
Arum, who promotes the Briton, has revealed the 35-year-old will make 'changes' to his game when they meet for a second time.

"I'd assume there'd be certain changes but that's up to Tyson and SugarHill [Steward] the trainer who I have great respect for, protege of the great Emanuel Steward," Arum told Sky Sports.
"I expect certain changes but what they are and how significant they'll be I don't know."
Fury has insisted he didn't deserve to lose to Usyk.
He said he felt he'd done enough to reign supreme, only for the result to be given the other way instead.

And Arum has backed the Gypsy King, insisting he also felt Fury had done enough. When it comes to the rematch, he's in no doubt over who will come out on top.
"We all felt over here [at Top Rank] and I was in Riyadh and I also felt it was going to be a very close fight," Arum said.
"Because I've known Usyk since he turned pro and I knew what a good, determined fighter he was and I followed him in his career because he's such a good friend of [Vasiliy] Lomachenko and they were always around together."
The 92-year-old added: "I thought he won a close fight but I could see it going the other way which it did.

"But Fury as he goes into training he's got to fight 12 full rounds. Because I thought the first part of the fight, it was no contest. It was all Fury.
"Then in the eighth round Usyk came on and won eight through 11 and I had Tyson come back and win the 12th.
"If Tyson trains well and goes 12 meaningful rounds, he should be able to beat Usyk."
Fury, meanwhile, has stoked the flames by dubbing Usyk an 'amateur boxer'.
Speaking to FUROCITY, he said: "I've watched the fight back lots of times. Still got the same answer - I thought I won the fight and thought I'd done enough. Usyk knows that he didn't beat me.

"It was close enough. One judge had me winning by a round and one of them had him winning by a round and that was the final decision.
"I thought I boxed the head right off him for most of the rounds.
"The fight was actually a lot easier than I thought it would be, a lot easier. People say he's a hard man to hit, I was landing three or four-punch combinations, laughing at him.

"My problem in that fight was that I was probably having too much fun. It was probably too easy. At times it was too easy.
"It was like I was in there with a local amateur boxer and I was just enjoying it too much and messing around.
"I paid the ultimate price round in round nine when I got a 10-8 round and got clipped. That's what happens when you're having too much fun. But I enjoyed it."
