The Oleksandr Usyk vs Tyson Fury rematch poster has been changed after fans raised concerns about the order of the main eventers.

As Usyk won their inaugural encounter in May and is the unified heavyweight champion, he has earned the right to be the A-side fighter.

Usyk beat Fury in their inaugural fight and so is expected to walk first and appear first on the postersGetty

However, when the poster rolled out on Wednesday night eagle-eyed supporters noticed that Fury‘s name was first.

One fan wrote: “How on earth’s Fury managed to blag his name first on the poster?

“Not ranked no.1, no belts, not undefeated, lost already to Usyk, not being staged in the UK so can’t claim he is the a-side or a ticket draw. What is Fury bringing to the table?”

Meanwhile, another punter tweeted: “Morning fight fans! What does everyone think about the Usyk vs Fury undercard?

“And why is it Fury’s name is first? Surely it should be Usyk as he is the champ, right?”

A few hours later, the poster was deleted and then re-uploaded with Usyk as the A-side.

The bill was accompanied by a full five-fight undercard for December 21, which includes two other heavyweight scraps.

In the co-main event, Serhii Bohachuk and Israil Madrimov square off in an excellent super welterweight contest.

Madrimov came up short against Terence Crawford in his last outing but pushed the two-weight undisputed champion all the way.

Meanwhile, Bohachuk dropped Vergil Ortiz twice en route to a narrow majority decision loss in August.

Further down the bill, Moses Itauma takes his biggest step up to date against Demsey McKean, who lost out to Filip Hrgovic in an IBF eliminator last time out.

Itauma is Britain’s most exciting heavyweight prospect and has been touted to take the reins from Usyk and Fury when they eventually hang up their gloves.

Another British heavyweight who has been making a lot of noise is Johnny Fisher.

He faces the experienced Dave Allen in the third fight of the night after dispatching Alen Babic inside 36 seconds three months ago.

The rest of the preliminary bouts include a British, Commonwealth and European super bantamweight clash between champion Dennis McCann and challenger Peter McGrail as well as Isaac Lowe vs Lee McGregor.
