It had to have been nerve-wracking for Chan Sung Jung going into UFC Fight Night 104. The man known as “the Korean Zombie” hadn’t set foot in the Octagon since his August 2013 defeat at the hands of Jose Aldo. He had rehabbed an injured shoulder, and dealt with the potentially career-derailing reality of conscription into the South Korean military. Three and half years later, Chan made the walk out into the Toyota Center in Houston, TX set to reanimate his his UFC career.
