Last week, Brazilian mixed martial arts legend Vitor “The Phenom” Belfort came out of retirement and signed a promotional agreement with Asian mixed martial arts company, ONE Championship.

And Belfort for whatever reason Belfort called for a cross-sport boxing match with former four division champion Roy Jones Jr.

For several years, UFC legend Anderson Silva was pushing for a boxing match with Jones - but UFC President Dana White was very reluctant to allow that bout to happen.

Back in 2017, the biggest and most financially lucrative cross-sport clash in history took place when Floyd Mayweather unretired to score a ten round stoppage over UFC star Conor McGregor.

“One fight I’d really love is me against Roy Jones Jr.,” Belfort told MMA Fighting.

“Roy, wherever you are, I wanna come challenge you for boxing match but with this condition: I’m gonna be able to dirty box with you.”

Jones has now responded. And he would be more than willing to face the 41-year-old Belfort - if given enough time to train properly.

The now 50-year-old Jones has been out of the ring since February 2018, but he's willing to dust off the gloves for one more fight.

"This is what I do for a living. Y'all must've forgot. That's who I am. I love a battle. I love a challenge. So, if that's what you want, that's what you get. Ain't like you gotta ask me twice," Jones told TMZ Sports.

Jones wants at least an eight week camp, but he believes just six weeks would be enough to beat Belfort.

"Well, I would like eight weeks, cause I like to get right. I need two extra weeks just to make sure I can showboat. But, six weeks, I can whip you," Jones said.

"I got nothing but the utmost respect for you. You were a helluva MMA fighter. You one of the best of all time. But, when it comes to boxing, this is what I do. I'm the ruler. I'm the king of this thing. Ya understand me? Since Muhammad Ali is not on Earth anymore, I don't think there's nothing ever on this Earth as bad as I am with these hands."
