Jose Aldo will not be released from his UFC contract, insists president Dana White.
Brazilian Aldo voiced his dissatisfaction at being overlooked for a rematch with featherweight champion Conor McGregor.
Outspoken Irishman McGregor defeated Aldo in just 13 seconds to win the featherweight title in December 2015 and has since fought Nate Diaz twice at welterweight.
Aldo beat Frankie Edgar at UFC 200 to be named interim featherweight champion and another bout with McGregor had appeared a possibility.
However, McGregor will instead do battle with lightweight champion Eddie Alvarez at UFC 205 at Madison Square Garden in November.
That prompted Aldo to tell Brazilian website Combate: "The biggest proof that who's in charge in the UFC now is Conor is that when I wanted to move up to fight [Anthony] Pettis, they said I'd have to vacate my belt and try this fight with no title whatsoever.
"But with him, they let him move up to the division above without losing his belt, and also let him do any fight he wants.
"Since I'm not here to be an employee of McGregor, I ask[ed] to cancel my contract with the UFC.
"When they offered me a fight with Frankie Edgar, Dana said that the winner would challenge McGregor or win the linear title, that he would lose his belt if he didn't return to the featherweight division after his rematch with Nate Diaz.
"After being fooled so many times, I don't feel motivated to fight in the UFC anymore."
But White, also speaking to Combate, said he is unwilling to grant Aldo a release from his contract.
"We won't cancel his contract," White said. "We know he got very emotional. We respect Jose Aldo very much. We care for the people around him.
"Khabib Nurmagomedov wanted a fight on the card and we got it for him. I'm sure we can find something nice for Aldo, as well."
