Last year, UFC superstar Conor McGregor made the sensational switch to boxing in order to fight Floyd 'Money' Mayweather, earning himself a tasty $100million in the process.
Ever since the fight, rumours have suggested that Mayweather could go the opposite way for a rematch, a move that would send shockwaves through the world of combat sports.
However, another boxing champion has also hinted at a possible switch to MMA, that being WBA, IBF and WBO heavyweight champion Anthony Joshua.
When talking to US talk show host Conan O'Brien, Joshua said: "It's not just about the money. If the people wanted it, and I felt in my heart it was the right decision, why not?
"I would have to train. I wouldn't just do it for a pay cheque, because this combat sport is serious, with things like concussions in the head and broken ribs.
"I’d have to take it serious.
"Why make the money if you can’t enjoy it? I would consider it if my heart told me it was the right thing for me."
The 28-year-old won gold at the 2012 Olympics and has reportedly earned a massive £43million in the sport since.
Joshua has headlined three stadium shows in the last year, in which he has beaten the likes of Carlos Takam, Joseph Parker and even veteran Wladimir Klitschko.
Joshua's next opponent, however, looks to be settled, as a clash between him and WBC heavyweight champion Deontay Wilder appears to be on the cards.
When visiting Wilder's home nation, Joshua also revealed that he has often been mistaken by American fans as a star from different sports.
He said: "They think I'm a basketballer, or I play NFL or something like that. Sometimes we play along to it, I just tell them that I tore my ACL.
"But some people, if you're into boxing, you'll know because the 'heavyweight championship of the world' title is well renowned. It's a big title to have and I've captured it and we're trying to secure the last one."
Given Joshua's stature, it's unsurprising that he has been mistaken for an NFL or basketball player.
Nevertheless, I'm sure Anthony Joshua's name will become a very familiar one to American punters very soon.
