Anthony Joshua will return to the ring against Daniel Dubois in September.

Carl Froch has used social media to reveal X-rated WhatsApp conversations he received from Anthony Joshua.

Joshua will return to the ring in September to face fellow Brit Daniel Dubois for the IBF title at Wembley Stadium.

Oleksandr Usyk, the undisputed heavyweight champion, surrendered the belt on Tuesday, elevating Dubois to champion status.

In a social media video, Usyk stated, “Anthony and Daniel, I know the IBF title is important to you.” It is my gift to you on September 21.”

On Friday morning, former Super Middleweight and WBC World Champion Froch took to social media to leak messages he received from Joshua.

He said: “So he’s called me a ‘pr***’ and I’ve gone back to him saying “who are you f***ing calling a pr***’?

“He’s come back and said ‘I don’t like you’ and fair enough, you don’t like me, but all I’ve done is been honest and given constructive criticism on what you’ve done since losing to Ruiz and Usyk, and where you’re going now you’re fighting Dubois.

“There’s no need to get personal, no need to start on a man’s hooter – looking pretty good by the way. And then you’ve got your £10 and £20 notes rolled out on your bed saying [‘get on my level, get on my level’ levels, it’s all about levels.”

Froch continued: “Where’s the humble guy gone? Where’s ‘remain humble, stay humble’? He’s talking about levels and says I’m not on his level. But he’s talking about money. Fair play to him – he’s made a fortune, he’s smashed it.

“But let’s talk about levels in terms of legacy and fights and career wins. A little fat kid from Mexico made him quit for f***’s sake. He spat his gumshield out and was looking around, looking for the corner, looking for the people in the crowd to help him out. He got punched from pillar to post. The referee is looking at him – ‘do you want to carry on, do you want to keep fighting?’ And what’s he done? He’s quit on his feet.

“That is embarrassing – something the Cobra would never, ever do. And he can take that to the bank!”
