News: Erik Koch injured, Frankie Edgar now faces Jose Aldo at UFC 153 in Rio Karim Zidan August 31, 2012 News The injury plague has struck yet another UFC main event. Roufus Sports standout Erik Koch has been forced to withdraw from his scheduled bout with Jose Aldo due to a training injury. His replacement will be none other than former lightweight champion Frankie Edgar. The switch was announced on the UFC website early Friday. “I’m pumped,” UFC president Dana White told USA Today. “I think that people are going to be very excited for this fight.”. “This main event is now not only a world title fight but also a super-fight that has long been a dream match for many fans,” said White. “Aldo and Edgar are two fantastic fighters who are always a part of the pound-for-pound debate.” Featherweight kingpin Jose Aldo has been out of action since a 1st round TKO over Chad Mendes back at UFC 142. A favorite in Brazil, Aldo will now get to fight in his homecountry for the third time when he faces Frankie Edgar in the main event of UFC 153. Frankie Edgar reigned as UFC lightweight champion from back in 2010 when he defeated UFC legend BJ Penn to capture the title. He would then go on to win a decisive rematch against ‘The Prodigy’ before entering into an epic couple of battles with Gray Maynard. Edgar would finally lose the title to Benson Henderson at UFC 144 in Japan as well as the rematch. UFC 153 takes place Oct. 13 at the HSBC Arena in Rio de Janeiro, Brazil.
