According to a report, UFC 163: Aldo vs. Pettis will take place in Rio de Janeiro on August 3rd.
UFC featherweight champion Jose Aldo will get to defend his title in Brazil for a second time, according to a report from Tatame. His bout with former WEC lightweight champion Anthony Pettis will take place at the HSBC Center in Rio de Janeiro, the same place he defeated Chad Mendes at back at UFC 142. It's expected that the event will be labeled as UFC 163.
Dana White mentioned last month that four locations were being considered for the Aldo/Pettis matchup - Vegas, Chicago, Texas, and Rio. It looks like Brazil won out. The UFC hasn't confirmed anything yet though, so plans still might change.
Aldo (22-1, 4-0 UFC) is coming off a unanimous decision win over Frankie Edgar at UFC 156. Pettis (16-2), who has competed at lightweight for his entire career, offered to drop to 145 after the Aldo/Edgar fight and his wish was granted by the UFC. Aldo was not impressed with the matchup and felt that there were more deserving featherweight contenders, but the UFC convinced him to agree to the bout by offering him a lightweight title shot if he's able to beat Pettis.
