The UFC returns to pay-per-view for the eighth time this year on Saturday night as ”UFC 163: Aldo vs. Korean Zombie” goes down at HSBC Arena in Rio de Janeiro. There have been several injury-ridden cards in 2013, but UFC 163 takes the cake. The original main event, as well as several main- and preliminary-card bouts, were changed in the weeks leading up to the event. Fortunately, the UFC’s lone undisputed Brazilian champion made it through training camp in one piece. Featherweight kingpin Jose Aldo (22-1 MMA, 4-0 UFC) looks to extend his remarkable winning streak to 13-0 since joining the Zuffa ranks in 2008 when he puts his belt on the line for a fifth time in the UFC, this time against Chan Sung Jung (13-3 MMA, 3-0 UFC).
