UFC featherweight champion Jose Aldo puts his belt on the line against Chan Sung Jung (aka the Korean Zombie) at UFC 163 on Saturday night in Rio de Janeiro, Brazil. First, Aldo, Jung, and the rest of the fighters had to make weight on Friday at the HSBC Arena. The champion and the challenger must weigh-in on weight or below to make a title bout official, and neither “No matter what people might think, I’m confident in my ability to win,” said Jung after stepping off the scale. The champion wasn’t lacking for confidence either. “I feel more confident with the crowd because the push me forward all the time,” said Aldo about fighting in front of his home country fans. “I don’t care what (Korean Zombie) is doing, how he’s training. I can’t be beaten here at home.” Lyoto Machida and Phil Davis square off in the night’s co-main event in a pivotal light heavyweight bout, the winner making a strong claim for a title shot.
