It’s going down.

Mike Tyson has recorded and shared his portion of “If You Show Up,” an upcoming collaboration with Chris Brown aimed as a diss track towards Soulja Boy.

“If you show up, it’s going down,” Iron Mike repeats on the cut. “I’m gonna teach him how to knock your ass down.”

Breezy is slated to record his verse this week with a music video to follow, according to TMZ.

Last night, Tyson revealed that 50 Cent was right in saying he would be training Brown for his upcoming bout with Young Draco.

“It’s confirmed. I’m training Chris,” said Tyson. “He chose me as his trainer to take on Soulja Boy. And Soulja Boy, what the fuck you talking about? The only thing I’m gonna teach him is to bite somebody’s ear? Yeah, that’s right! I’m gonna teach him every dirty trick in the book to knock you out.”

Meanwhile, Soulja has been pumping iron in preparation for the fight, which he claims will take place at the MGM Grand in Las Vegas in March. The rapper shared his workout regimen on Snapchat, hitting the weights and mixing it up with cardio on a treadmill.

“Training to get ready for the big fight,” says Soulja. “It’s going down. Make sure you get your tickets on pay-per-view. We working every day. The training don’t stop. The Money Team, we’re in the gym every day. We’re getting it in.”
