During the UFC on FX 8 post-fight press conference, UFC executive Marshall Zelaznik confirmed that UFC 163 will take place on August 3rd in Rio de Janeiro, Brazil. Featherweight champion Jose Aldo will defend his title for a 7th consecutive time (dating back to the WEC era) against lightweight contender Anthony Pettis, who is making his featherweight debut. Pettis joins Frankie Edgar and Kenny Florian as 145 lbs title challengers who previously had 1 or no fights in the division.
Also official for the card is a long rumored welterweight fight between Demian Maia and Josh Koscheck. The resurgent Maia is 3-0 in his new weight class, and recently sent Jon Fitch out of the UFC with an impressive decision win at UFC 156. Koscheck was defeated by TKO vs. Robbie Lawler at UFC 157, giving the former #1 contender consecutive defeats for the first time in his MMA career.
More details such as tickets, additional fights, etc. will be announced over the next few weeks. Anthony Perosh and Vinny Magalhaes are looking to fight each other at UFC 163, but the matchup has to be finalized.
