Aldo (22-1) is currently undefeated in his last 15 bouts. This will be his eighth straight title fight, and his fifth defense of the UFC Featherweight Championship.
The Korean Zombie (13-3) gets the title shot by virtue of an injury to Anthony Pettis. Jung has won three straight fights in the Octagon, and all have been finishes. That includes a 2011 Submission of the Year contender and a 2012 Fight of the Year contender with Dustin Poirier.
