It looks like the UFC’s featherweight division will be without one their more popular fighters for the next few years.

On Monday, Chan Sung Jung, more commonly known as the ‘Korean Zombie’ by the fight fans, took to his Facebook to announce he has been ordered to complete mandatory military service in his native country of South Korea. This type of military service is required by all male South Korean citizens.

As a result, the former title contender will not be able to participate in any MMA bouts for the next two years.

Jung (13-4), currently the number six ranked featherweight according to the UFC fighter rankings, was last seen suffering a dislocated shoulder in the fourth round of his UFC 163 title fight with champion Jose Aldo.

This loss snapped Jung’s three-fight win streak, which included a 2011 Submission of the Year over Leonard Garcia, a UFC record seven-second knockout of Mark Hominick and a 2012 Fight of the Year performance against Dustin Poirier. He also earned the 2010 Fight of the Year in his split decision loss to Garcia back at WEC 48

He was originally scheduled to make his long-awaited return from injury against Akira Corisanni at UFC Fight Night 53 before another injury forced him out of the bout.
