Two changes to Phoenix fight card

Injuries have forced a pair of changes to the Jan. 15 UFC Fight Night card in Phoenix, the promotion announced today.

In the flyweight division, it will be a new clash of contenders, as former world title challenger John Moraga replaces the injured Jussier Formiga against Milwaukee's Sergio Pettis.

Plus, with Jordan Rinaldi forced to withdraw from his match against Devin Powell, unbeaten Drakkar Klose has stepped in to make his Octagon debut against his fellow UFC newcomer.

UFC Fight Night, which takes place at Talking Stick Resort Arena, is headlined by the featherweight clash between UFC Hall of Famer BJ Penn and Mexican phenom Yair Rodriguez. FS1 will televise the special Sunday UFC Fight Night event.
