UFC Chairman Lorenzo Fertitta told The Times on Thursday that Aldo has recovered from a neck injury that caused his scheduled Aug. 2 defense against Mendes to be delayed.
Aldo (24-1) beat Mendes (16-1) by first-round knockout on Jan. 14, 2012, in Rio de Janeiro. Mendes has responded with five consecutive victories, four by knockout.
Although Staples Center has an open date Oct. 25, Fertitta said he was obligated to place a major UFC fight in Brazil for the UFC's broadcast partner in that country, Globo.
"Staples is at the top of our list," Fertitta said. "We love being at Staples. It's a priority for us. We're going to try and get back at Staples within a year."
