RIO DE JANEIRO – MMAjunkie.com (www.mmajunkie.com) was on scene for today’s official fighter weigh-ins for UFC 163, where all but one competitor successfully made weight for Saturday’s card. In the main event, UFC featherweight champion Jose Aldo defends his belt for the fifth time in the UFC and seventh time overall when he meets “The Korean Zombie,” Chan Sung Jung. Jung was tapped for the fight when Aldo’s original opponent, Anthony Pettis, was injured in training and no longer could make the fight – he was dropping from lightweight to featherweight for the first time. Aldo, fighting in his home country of Brazil for the second time as champion, weighed in at the title-fight maximum of 145 pounds.
