UFC on Fox: dos Santos vs. Miocic

UFC on Fox: dos Santos vs. Miocic (also known as UFC on Fox 13) was a mixed martial arts event held at U.S. Airways Center in Phoenix, Arizona, on December 13, 2014.

Background
The event was the first that the organization has hosted in Arizona. Zuffa previously hosted the final World Extreme Cagefighting event, WEC 53, in nearby Glendale in 2010.

The fight card was headlined by a heavyweight bout between former UFC Heavyweight Champion Junior dos Santos and Stipe Miocic.

Jussier Formiga was expected to face John Moraga at the event. However, Formiga was forced to pull out of the fight due to injury and was replaced by UFC newcomer Willie Gates.

Nate Diaz missed weight on his first attempt at the weigh-ins, weighing in at 160.6 pounds. He was given additional time to make the lightweight limit, but made no attempt to cut further. Instead, he was fined 20 percent of his purse, which went to Rafael dos Anjos.

A middleweight bout between Ed Herman and Derek Brunson, slated for the televised preliminary portion of the event, was cancelled on the day of the event, as Brunson was stricken with a stomach ailment. The fight was rescheduled to take place the following month at UFC 183.
