There is a massive 8kg difference between Kiwi heavyweight Joseph Parker and British opponent Dillian Whyte ahead of their showdown in London on Sunday morning NZ time.
Parker and Whyte will square off in front of a sold-out crowd at London's O2 Arena in what will be a career-defining fight for both fighters.
Parker weighed in at 110kg, 3kg heavier than his last fight against Anthony Joshua in April. His opponent Whyte weighed in at 118kg, 2.26kg heavier than his last fight against Australia's Lucas Browne.
A win for either fighter would put them in pole position to challenge for Deontay Wilder's WBC championship, and Joshua's WBO, WBA and IBF belts.
Despite the weight difference, Parker's trainer Kevin Barry is confident the 26-year-old Aucklander will win by knockout as he looks to avoid back-to-back defeats after losing his WBO world title to Joshua in Cardiff.
That was Parker's only blemish on an otherwise unbeaten record, a fact he shares with London's Whyte, whose sole defeat also came against Joshua, back in December 2015.
"I think we are in a very tough fight, but I think Joe is right where I want him to be," Barry said.
"I'm supremely confident. Joe is confident. The team around us is confident. I really feel we are going to have a great performance tomorrow night.
"We'll be going for a knockout that's for sure. We haven't had one in the last four fights.
"I can promise you that Joe is going to be hitting this guy with every piece of energy in his body."
