We knew it was happening, now we know when (and where).

Ultimate Fighting Championship (UFC) has booked Vitor Belfort vs. Luke Rockhold as the main event for UFC on FX 8: "Belfort vs. Rockhold," on May 18, 2013 at Arena Jaragua in Santa Catarina, Brazil.

Tatame confirmed the booking details earlier today.

Belfort (22-10) is fresh off a TRT-powered ass kicking of Michael Bisping at the UFC on FX 7 event earlier this year in Brazil. "The Phenom" could be a couple of wins away from a rematch against Anderson Silva, he just has to fulfill this obligation first.

Could Rockhold be one of those "top guys?"

The American Kickboxing Academy (AKA) standout enters the Octagon with a 10-1 record and having never lost under the Strikeforce banner. In addition to being the last man to hold the now-defunct promotion's 185-pound strap, Rocky boasts wins over Ronaldo Souza and Tim Kennedy.

He's definitely got skills, but are they up to par with the rest of the division?

Unlike Gilbert Melendez, who was able to walk right into a title shot, Rockhold won't get a crack at "The Spider" like he was hoping for, but it would be hard to deny him one if he upsets Belfort in front of a hometown crowd. Heck, a finish might damn near guarantee it.

That is, unless Chris Weidman has something to say about it first.

No other match-ups have been announced for the promotion's return to Brazil at this time; however, keep it locked in to MMAmania.com and we'll bring you up to speed on all the breaking news as it develops.
