Iron Mike, who once chewed Evander Holyfield’s ear, confirmed he is mentoring R&B superstar for his three-round bout against hip-hop icon

MIKE TYSON has warned Floyd Mayweather that he will teach Chris Brown how to bite off Soulja Boy’s ear.

Iron Mike is mentoring the R&B star for his showdown with the hip hop icon and pledged to show Brown “every dirty trick”.

The pair will square up in New York in March and the fight will be available on pay-per-view.

And though the music stars have genuine grievances with each other, Tyson appeared to ramp everything up even more with his sinister promise.

The former heavyweight champion of the world, 50, famously bit off a chunk of Evander Holyfield’s ear in their June 1997 bout.

And he will now teach Brown how to do the same.

Speaking on an Instagram video, Tyson said: “So it’s confirmed I’m training Chris Brown.

“We’re taking on Soulja Boy. And Soulja Boy what the f*** you talking about?

“Only thing I’m going to teach him is to bite somebody’s ear? Yeah, that’s right.

“I’m going to teach him every dirty trick in the book to knock you out because I’m not going to teach him how to run.”

That final comment was taken by some as a dig at Mayweather.

Money has been accused of dodging fighters in their prime and “running scared” since Conor McGregor got his boxing licence.

The musicians are fighting because of a social media feud that erupted win Soulja Boy liked an Instagram photo posted by Brown’s ex-girlfriend Karrueche Tran.

The duo then had a long war of words on social media with Soulja Boy also calling out Brown’s daughter Royalty following which Brown accused Soulja Boy of being a drug addict and a police informant.
