McGregor: 'Scared' Aldo should forfeit title after withdrawal
Conor McGregor accused Jose Aldo of being 'scared for his life' after the Brazilian withdrew from his scheduled UFC title defence against the Dubliner.
The featherweight champion has cited a rib injury as the reason he cannot face McGregor in Las Vegas in less than two weeks' time.
Former two-time title contender Chad Mendes will instead step into Aldo's place and fight McGregor for the interim featherweight title.
Seven-time defending champion Aldo suffered the injury while training last week in Brazil.
Following initial rumours of the fight being cancelled, Aldo attempted to recover in time to still compete on the pay-per-view card, but was forced to pull out.
"Aldo's rib is too painful and he will not be fighting," UFC president Dana White said.
"It's (Aldo's) decision. I don't feel great about it.
"We've spent a lot of money promoting this fight and a lot of people were excited. It's definitely disappointing."
McGregor reacted to the news characteristically bullish fashion, commenting: "If a man is scared for his life, we can not force him to step inside and fight me.
"Doctors have cleared him to fight - it's a bruise - but he still pulled out.
"The belt should be taken from him and we will contest for the interim belt or, in my opinion, the real belt."
His previous advice was: "A little bit of ibuprofen and a little bit of toughen the f**k up."
McGregor went on to predict a four-minute knockout over Mendes while also adding simply on Twitter: "They can run. But they can't hide."
The Irishman is 5-0 in the UFC, with four knockouts.
Elsewhere, after the huge success of the UFC event in Dublin in July 2014, promoters have announced a new show for October 24 at the 3 Arena.
No fights have been confirmed or lined up for the night, but it is unlikely that McGregor will feature.
Other Irish fighters such as Cathal Pendred, Neil Seery, Paddy Holohan and Joseph Duffy are all expected to be involved.
McGregor became a household name last July when he knocked out Diego Brandau at the 3 Arena in front of a bumper crowd.
