Tyson Fury will weigh in at least 20lbs 'heavier than last time' for his trilogy fight with Deontay Wilder, according to his trainer SugarHill Steward.
Fury, 33, will face Wilder, 35, for the third and possibly final time on October 9 at the T-Mobile Arena in Las Vegas.
The Gypsy King told reporters at a press conference in June that he will tip the scales at a whopping 300 lbs at the weigh-ins on Friday.
And while Steward insists that isn't the case, he did admit that Fury will be over a stone heavier for his trilogy bout against Wilder than he was in their rematch.
"It’s not going to be 300 pounds, it’s probably going to be like 290 or something but not 300 exactly," Steward told Vegas Insider.
"Heavier than last time by 20 pounds or so, why not?
"The bigger the better, the heavier the stronger.
"He’s training with that weight, he’s built up.
"It’s not like he’s just putting on fat, it’s building up muscles.
"The bigger the better, the heavier the stronger."
Fury is driven and motivated by fear, according to Steward, the nephew of legendary boxing coach Emanuel Steward, as he prepares for his trilogy fight with Wilder.
"There’s always that fear factor, you’ve got to have that," he insisted.
"That’s what keeps you sharp. You have got to have that.
"That’s not to say you believe it always or you’re afraid of anyone, but to keep you sharp it's a really important thing."
And Steward also expects to face the best version of The Bronze Bomber on Saturday night.
He continued: "I have to consider everything.
"We’re preparing for the best Deontay Wilder that he can be. Let’s just say he’s improved so much. You can’t go in there and think anything less.
"We’re preparing for him to come in at the highest peak of his abilities and that's how we’re training and preparing - for the best Deontay Wilder."
Fury, 33, stopped Wilder in the seventh round last February.
And he is confident he can repeat the same feat against the 'one-trick pony' this weekend.
Fury said: "I gave my game plan away the first time because he wasn’t good enough to do anything about it.
"And I’ll do the same thing this time because he's not good enough to do anything about it.
"Deontay Wilder is a one-trick pony. He's got one-punch power, we all know that - great.
"But what I'm going to do to Deontay Wilder this time is I'm going to run him over as if I’m an 18-wheeler and he's a human being.
"I guarantee he does not go past where he did before [the seventh round].
"Because before, I only had five or six weeks of practicing what I'm going to do to him.
"This time, I’ve had 18 months of practicing what I'm going to do to him.
"So I anticipate it's going to be like an 18-wheeler running over somebody, and that's what you're gonna see.
"I’m building my weight up, trying to get up to 300lbs for this fight.
"Because I’m looking for a big knockout straight away."
