Zhilei Zhang weighs almost five stone heavier than Deontay Wilder in Riyadh

ZHILEI ZHANG will be a staggering 68.2lb lighter than Matchroom captain Deontay Wilder when they clash in Riyadh on Saturday night.

The two heavyweights will face off in the fifth and final match of the unprecedented Matchroom v Queensberry event to be held at the Kingdom Arena.

Both men are coming off decision losses to Joseph Parker and Wilder has described the fight as a retirement match for whoever loses this time.

And the Bronze Bomber weighed almost five stone lighter than Zhang as he tipped the scales at 214 1/2lbs while Zhang came in at 282 3/4lbs. The Chinese southpaw was 8 3/4lbs lighter than when he lost to Parker.

But it was very close when the other two heavyweights of the sport faced each other before they fought for the interim IBF title. Undefeated Filip Hrgovic, representing Team Matchroom, weighed in at 247 1/2lbs and Daniel Dubois was a little more than two pounds lighter than his career heaviest at 245 3/4lbs.

There was no problem with WBA featherweight champion Ray Ford making weight, despite his insistence that he is ready to move up to 130lbs. Instead, he again made a successful featherweight, coming in at 125 1/2lbs in a defense against Queensberry's Nick Ball, who had 125 3/4lbs.

At middleweight, the undefeated pair of Hamzah Sheeraz and Austin 'Ammo' Williams both weigh in at 159 1/2lbs ahead of what many are calling a potential fight of the night. Sheeraz is Queensberry's 160lb prospect and has been named captain of the Queensberry team, but Williams, who wore the hat for the event, knows that victory will propel him towards the world title.

At light-heavyweight, long-time Matchroom man Craig Richards was 174 1/4lbs and 17-1 Willy Hutchinson was also comfortably inside the limit at 174lbs.

It wasn't so comfortable for WBA light-heavyweight champion Dmitry Bivol, who puts his title on the line against Malik Zinad in the only fight on the card that isn't a fight between Frank Warren and Eddie Hearn.

Bivol was supposed to fight Arthur Beterbiev here but Zinad, who weighs 174 1/4lbs, was inserted when the Russian withdrew due to injury. But Bivol, 33, has been on the 175lbs limit and knows a win here should set up a long-awaited unification clash with Beterbiev next.
