Anthony Joshua weighed in at a career-heavy 18st 3lb for Saturday's bout against Jermaine Franklin, which Eddie Hearn suggested was a sign he had "bad intentions for this fight".
Heavier than at his previous top weight of 18st 2lb for his 2017 clash with Carlos Takam, Hearn anticipates an "explosive knockout" from Joshua at O2 Arena.
By contrast, Franklin has lost 23lb since facing Dillian Whyte, weighing in at 16st 7lb to seemingly give Joshua a clear advantage in terms of power, if not mobility.
"There's always an over-analysis with his weight, but clearly he's come in with bad intentions for this fight," said promoter Hearn.
"In some fights, where you need speed and agility, he comes in lighter. But I think you're going to get an explosive knockout."

Joshua is backing himself for the same, adding: "I know I've got the possibility of doing it, but there's a process to get there. I just follow the process."
Franklin claimed to have "a chin of steel", but that is set to be put to the test by the focused Briton, who has vowed to retire if he loses.
"I've got my gameplan, got my mind right, and I'm ready to go for war," Joshua said.
