Last week, Soulja Boy announced that he had successfully recruited Floyd Mayweather to train him for his upcoming boxing match against Chris Brown. Now, Mike Tyson has heeded 50 Cent's call to train Brown.

Tyson announced the news Sunday night via Instagram. 

“So it’s confirmed,” he said in a video message. “I’m training Chris, he chose me as his trainer to take on Soulja Boy. And Soulja Boy, what the fuck you talking about? I’m gonna teach him how to bite somebody’s ear. Yeah, that’s right. I’m gonna teach him every dirty trick in the book to knock you out. I’m not going to teach him how to run."

Tyson became the youngest heavyweight boxing champ ever in 1986, at age 20. He will certainly be a boon to Brown's chances. Meanwhile, it looks like Soulja Boy's training regimen is in full swing.
