LONDON, England — Ring Magazine's pound-for-pound No. 1 Oleksandr Usyk registered his career-heaviest ahead of Saturday night's Wembley Stadium showdown with Daniel Dubois set to be streamed live on DAZN PPV.

Usyk, the Ring, WBO, WBA and WBC heavyweight champion, came in at 227.3 pounds, eclipsing his previous highest weight of 226, which was for his victorious rematch with Tyson Fury.

Dubois, who puts his IBF title on the line, tipped the scales at 243.8 which is a full 10lbs heavier than he was for his first clash with Usyk, when he was stopped in the ninth round.

It was, however, a drop of 5lbs from the weight he was for his previous outing, when he crushed Anthony Joshua at Wembley Stadium in September.

Dubois, who has seemed light and lean all week, said: "I'm locked in, I'm focused, I can't wait. I'm going to win by any means necessary."

Usyk, who has revealed he will have just one more fight after Saturday night, kept it short and sweet: "For me this is a great opportunity for my people and my country. See you tomorrow."

Like Usyk, former world cruiserweight and bridgerweight champion Lawrence Okolie also came in at his heaviest ever when he weighed 262.4 ahead of his chief support clash with Kevin Lerena, who was 30lbs lighter at 232.5.

The pair were supposed to fight as cruiserweights and then bridgerweights, but they have finally agreed to meet as full-fledged heavyweights.

South African Lerena, a huge underdog, said: "When my left hand lands on his temple or his chin, he’s going to sit. If I hurt him and get the opportunity, it's my duty to finish him."

Okolie’s prediction was simple: "Lawrence Okolie by stoppage."
