That's the word from the featherweight champ Aldo's camp:

Aldo's manager, Ed Soares, confirmed when appearing on MMAWeekly Radio, that the Brazilian was likely coming back for a September fight, and Gamburyan was the probable opponent. 

"He should be fighting sometime in September I think. I think that's the fight," said Soares about a fight with Manny Gamburyan. "That's the fight that makes sense, I also heard there were some rumors about that (Josh) Grispi kid moving up the ranks there too, but I think Manny lately has been pretty impressive. People do what they want to do, but I think Manny seems like the right fight as far as the pecking order goes."

WEC 51 is also the target date for Miguel Torres's next fight, as well as Donald Cerrone and Leonard Garcia. While no match-ups have been announced, nor has a city or venue been selected for the event, the card is scheduled for September 8.
