The UFC on FOX 13 Weigh-Ins took place today in Phoenix, Arizona and the heavyweight main event is now official after both fighters made weight. 
Today’s weigh-ins came from the Phoenix Convention Center and tomorrow night’s fight card will come from the US Airways Center.
The event will be headlined by a heavyweight bout as former UFC champion Junior dos Santos (242 lbs) steps into the octagon since losing to Cain Velasquez last year as he will meet Stipe Miocic (243 lbs) in a scheduled five round bout.
The only fighter to miss weight was lightweight Nate Diaz (160.6 lbs) for his co-main event bout against Rafael dos Anjos (156 lbs). Diaz will be fined 20 percent by the commission for missing weight and the bout will go forward as a catchweight bout.
