Mark Chamberlain has welcomed Jack Rafferty's call for a high stakes junior welterweight showdown on the undercard of the undisputed heavyweight title fight between Oleksandr Usyk and Daniel Dubois.

Usyk, the reigning WBC, WBA, WBO and Ring Magazine champion, will rematch IBF titleholder Daniel Dubois at London's Wembley Stadium on July 19.

Earlier this week, Rafferty (26-0, 17 KOs), undefeated British and Commonwealth champion, told The Ring he feels a fight with Chamberlain (17-1, 12 KOs) is worthy of such an occasion.

The news came as no surprise to Chamberlain. In fact, the 26-year-old revealed that he too has asked about the possibility of the fight landing on the same show.

In April, Chamberlain made his junior welterweight debut on the same bill as Rafferty’s successful Commonwealth title defence against Cory O’Regan.

The two were sat next to each other at the pre-fight press conference and a future fight was a major talking point.

"It's no secret, obviously," Chamberlain told The Ring.

"We were meant to fight on the 7th of June [on the Fabio Wardley vs. Justis Huni undercard]. It was put towards us both when we got out of the ring in April. We both agreed to it and that's as far as it went really, no more got said.

"Obviously, they're using their brains a little bit because with it being a Riyadh Season show the money makes sense and, like Jack said, it's a big fight and it's worth more.

"I couldn't care, I'd fight him in the telephone box but at the end of the day it's a big fight, isn't it? It's a tough fight. If the numbers make sense, why not?”

Chamberlain made his name as a heavy-handed, exciting lightweight. He caught the eye of Turki Alalshikh, head of Riyadh Season, and was handed the opportunity to perform on the undercard of the massive heavyweight showdown between Anthony Joshua and Francis Ngannou in Riyadh, Saudi Arabia.

The southpaw took his chance and scored an impressive fourth-round stoppage of former European champion Gavin Gwynne. Two months later, he was back in the Saudi capital and knocked out Joshua Wahab inside a round.

Things were going perfectly until he suffered a 10-round upset defeat by Josh Padley on the undercard of Daniel Dubois' fifth-round knockout of Joshua at Wembley last September.

That result persuaded Chamberlain to leave the lightweight division behind and seek his fortune at 140lbs.

A month after Chamberlain lost his undefeated record to Padley, Rafferty stopped then-unbeaten contender Henry Turner to add the British title to his Commonwealth belt and has since notched up two more stoppage wins.

A fight between the two seems an inevitability and both have come to the conclusion that, if possible, they might as well do it on the biggest stage imaginable.

"That's exactly what it's all about, isn't it? I've got nothing to say about him. There's respect there and obviously we're going to get in there and punch each other's head in and get paid for it. It's as simple as that so it makes no odds to me,” Chamberlain said.

"It's a good domestic fight. Both British for the British and Commonwealth titles. Like I say, it all boils down to money at the end of the day and I'm sure he'll say the same.

"He's already said in an interview that he'll only fight me for x amount. It is what it is, isn't it? It's a business and everyone's in it for money. We all want to make as much money as we can and get out so, yeah, I'll fight anyone for the right money. It's as simple as that.

"We're both under Frank [Warren], Frank's my manager. There's no reason why this fight can't happen."
