The UFC was forced to make a pair of changes to the upcoming Fight Night card in Phoenix due to injuries.
The promotion announced that Brazilian flyweight Jussier Formiga was forced out of his bout with Sergio Pettis due to an undisclosed injury, and will be replaced by John Moraga on Jan. 15.
Moraga (16-5) looks to get back on track following consecutive losses to Matheus Nicolau and Joseph Benavidez, while Pettis (14-2) goes for his third straight win as a flyweight after decision victories over Chris Cariaso and Chris Kelades.
Devin Powell also has a new opponent in Phoenix.
