Nothing personal, just business.

Former Strikeforce Heavyweight Antonio Silva is getting a fresh start in mixed martial arts (MMA) as the newest addition to the Ultimate Fighting Championship (UFC) roster. He's looking to rebound from a knockout loss to Daniel Cormier in last year's grand prix tournament by taking on Roy Nelson at the UFC 146 pay-per-view (PPV) event on May 26 in Las Vegas.

But he won't be training for "Big Country" with the Blackzilians.

That's because "Bigfoot" skipped town when he heard that Alistair Overeem, who also competes at UFC 146 in a heavyweight title fight opposite Junior dos Santos, would be setting up shop in the place he called home.

From MMA Weekly:

"I always take care of my camp and make sure I'm surrounded by the right people. I was training at Blackzilians and yes, I think it's inevitable, Alistair Overeem and I are on a collision course. There is a possibility of us fighting one another one day so that when I heard that he was going over there, I decided to take my camp elsewhere."

Silva doesn't want Overeem learning any trade secrets should "Pezao" overcome Nelson and work his way up the ladder, culminating in an eventual showdown against "Demolition Man."

More from "Bigfoot" after the jump.
