New Zealand's Joseph Parker has tipped the scales at a career-high 251lbs ahead of his heavyweight rematch against eccentric but dangerous Brit Derek Chisora as he seeks to get back into the world heavyweight title picture.

Parker, the former WBO champion, recovered from being knocked down inside the opening 10 seconds by Chisora's overhand right in their first bout in May to claim a paper-thin split decision following a hard-fought contest.

With a second world title shot not forthcoming, Parker has plumped for a return fight against Chisora and, as he seeks to take the judges out of the equation, the New Zealander has come in nearly 10lbs heavier than the first meeting.

As well as a 3lb weight advantage at the AO Arena in Manchester, Parker (29-2, 21KOs) has the edge in height and reach and is bullish that he will beat the British veteran in more emphatic fashion on Saturday night.

"I back myself with my power and speed, I have confidence going into this fight and it will be a different fight. I just feel like I'm going to break him down, get him tired and knock him out," said Parker.

"As an opponent, Derek is as tough as they come. He comes forward, puts on a lot of pressure, he's probably the best pressure fighter I've fought. He comes and just throws big bombs and he does that from round one to round 12.

"I thought I won the last fight but it was close and this time I want to make it a lot clearer. I know he's going to bring a similar game plan and I'm prepared for it."

A more comprehensive victory over Chisora (32-11, 23KOs), who opted to play music at the final press conference on Thursday rather than speak, is unlikely to open the door to another world title tilt for Parker any time soon.

Tyson Fury, the WBC champion, is slated to next take on Dillian Whyte, who has beaten both Parker and Chisora, while Oleksandr Usyk is contractually obliged to defend his IBF, WBA and WBO titles against Anthony Joshua.

Parker said: "I'm taking it fight by fight, I don't care who it is after, but I just want to focus on Derek. The world title's there, later on if I can fight for it, but I just want to take it fight by fight and enjoy it."
