Anthony Johnson currently holds both the IBF and WBA Heavyweight Titles, recently coming off of a victory over the now retired Wladimir Klitschko this past April.
The two promotion boxing champion is considering a run in mixed martial arts, although he feels that he would get beaten.
"I like fighting, I'd do whatever," said Joshua to Sky Sports. "I'd probably get beaten. The only thing that they can't do is submissions, but they can kick, elbow, bite - whatever they want. Just no submissions. I can't beat a guy (via submission). That takes a lot of time to learn the skills and submissions, which I don't have the time for, but when it comes to pure aggression and fighting rules, I can definitely fight, so I don't mind that.”
Joshua has been challenged to a boxing super fight by UFC Heavyweight Champion Stipe Miocic, the fighter has yet to accept or turn down the challenge.
Professional boxers haven’t had much success crossing over into MMA and that is something Joshua is aware of.
"It wouldn't be a problem. If you look at most boxers who've crossed over to MMA, they get beaten on the ground. James Toney, Roy Jones, they were phenomenal boxers but they just couldn't compete in the cage because of the 'ground and pound' game,” says Joshua.
It won’t be a few months before Joshua is expected to defend the IBF Heavyweight Title because he is expected to fight Kubrat Pulev this October.
