The event, which is loaded with Brazilian fighters, will take place at the HSBC Arena in Rio de Janeiro and will be headlined by a featherweight title bout between champion Jose Aldo and No. 5-ranked Chan Sung Jung.
Aldo (22-1) has defended his title six times since taking the belt from Mike Brown in November 2009 while fighting under the WEC banner. Aldo and his title transferred to the UFC when that promotion was absorbed by the UFC.
Jung (13-3) is in the midst of a three-fight winning streak. Each of those victories has earned him at least one fight-night bonus. His most recent win, a 2012 victory over Dustin Poirier, gave Jung the rare double-up, earning him Fight of the Night and Submission of the Night honors.
The co-main event will be a matchup between two of the top light heavyweights in the UFC, as No. 1-ranked Lyoto Machida faces No. 7-ranked Phil Davis.
