When it was announced that Anthony Pettis was injured and forced out of the UFC 163 featherweight title fight with champion Jose Aldo , some were surprised when “The Korean Zombie,” Chan-Sung Jung , was named as Pettis’ replacement. In fact, Jung was one of them. “At first, I was really in disbelief about it, and so until Dana White actually announced that I was going to be in the fight, I actually didn’t really even believe it, but it was true. But the excitement lasted quite a while,” said Jung on a recent media conference call promoting the event. Jung was originally scheduled to face Ricardo Lamas at UFC 162, but was pulled from the fight to face Aldo.  Lamas is ranked higher than Jung and many felt Lamas should have been Pettis’ replacement.  Jung doesn’t disagree, but believes more than just rankings were factored into the decision
