Chris Weidman vs. Vitor Belfort official for UFC 181 main event on Dec. 6 in Las Vegas

About 15 minutes after Nevada State Athletic Commission (NSAC) granted Vitor Belfort a license to compete in mixed martial arts (MMA), Ultimate Fighting Championship (UFC) announced "The Phenom" as the next challenger for the promotion's middleweight champion, Chris Weidman.

When and where?

The main event of the UFC 181 pay-per-view (PPV) event, which is scheduled to take place on Dec. 6, 2014 in Las Vegas, Nevada. As "The Phenom" revealed during today's hearing (live blog and updates here), the promotion already secured verbal agreements and was simply waiting for NSAC to rubber-stamp the proceedings.

Belfort talked to UFC.com about his big day:

"After a big storm comes the rainbow, so I'm pretty happy. No whining from me, I'm happy. I worked hard for this moment and the moment will come. Now I'll just take care of today. Winning every day is how I will prepare. Whatever I can implement to get better every day, that's what I will do. I don't think too much about [Weidman]; I'm more focused on me. And to win, I have to see what I have to do; I'm not focused on him. Winning the (UFC 12) tournament at 19 years old, becoming the light heavyweight champion, and now fighting for the middleweight title, it's been an amazing journey."

No other bouts have been made official at this time; however, the Anthony Pettis vs. Gilbert Melendez lightweight title fight is rumored to be the UFC 181 co-headliner (more on that match up here). Expect more bouts to be announced in the coming days.

Until then, it's Weidman vs. Belfort for all the marbles.

Who ya' got?
