Aldo's willingness to move up made UFC president Dana White's job very easy and now he will begin the process of putting the fight together as soon as Pettis is cleared to return to action following knee surgery.
"Sounds like we've got a fight," White said. "That was easy, we got that deal done. One more thing I don't have to do on Monday."
Moments after White made that declaration he got a message from Pettis, who was watching the fights at home in Milwaukee.
"Anthony Pettis just called — he said he absolutely, 100-percent wants the Aldo fight and he'll take it. So there you go," White said.
As far as Aldo's title goes, White didn't relent on an earlier statement he made saying that if the Brazilian moves up to lightweight to challenge for the belt that he would have to relinquish his belt at 145 pounds.
If he loses, however, White said Aldo can go back down to 145 pounds if he chooses and challenge for the title again if he wants.
"The answer is yes — he would vacate the title, move up to 155, fight for the title, if he didn't win the title he could go back and challenge for the 45-pound title again, if he wanted to do that. Or he wins the 55-pound title and two other guys will fight for the 45-pound title," White said.
