Joshua Buatsi and Craig Richards are both in incredible shape ahead of their all-British light heavyweight bout.

The two Brits are set to battle it out in London this Saturday in a good old domestic dust-up.

And they have both clearly been putting in the hard work in the gym to help to get themselves in the best shape they possibly can for this career-defining fight.

Matchroom Boxing's official Twitter account showed off their incredibly ripped physiques, sharing the images to their some 500,000 followers.

They captioned the post "READY" followed by a fire emoji and the hashtag #BuatsiRichards.

Buatsi, 29, has not fought since he battered Richard Bolotniks into an 11th-round stoppage in Hearn's back garden last summer.

Richards meanwhile has won 17 out of his 20 fights - losing two and drawing one.

Buatsi has 13 knockouts on his record compared to Richards' 10, with both men boxing out of an orthodox stance.

But the Ghanaian-born boxer has the slender advantage when it comes to height and reach.

Buatsi stands at 6 ft 2 in, just an inch taller than opponent Richards, and also boasts a slightly longer reach by an inch and a half.

Either way, it's almost certainly going to be a cracker, with promoter Eddie Hearn barely able to contain his excitement.

Speaking at a press conference to promote the fight, he said: “Joshua Buatsi, Olympic bronze medallist against Craig Richards, a man who’s won British titles, challenged for the world title as well.

"This is a kind of fight that gets me excited, this is the kind of fight that seems so obvious.

"Two brilliant domestic fighters but also two world class fighters as well.

“A world title challenger in Craig Richards and a man that many believe is destined for greatness at 175lbs.

"I want to thank to teams of both fighters; you need to understand these guys know each other.

"One from Croydon and one from Crystal Palace, a stone’s throw from each other and they’ve known each other for many years.

“Sometimes in boxing they don’t want to make these fights, trainers, managers, advisors, fighters - 'we’ll wait for our world title shot'.

"You need to stop waiting, fighters out there that are queuing up for a world title shot that is not imminent, don’t stall your career when you could be involved in brilliant fights, fights that could take your career to another level.

"That’s what we’ve got May 21 in London.”
