Even though Aldo's injury is serious enough to justify his withdrawal, McGregor could not resist taking a few sucker punches at the champion.
"The Irish, we never lie," McGregor, who will now face Chad Mendes for the interim featherweight title at UFC 189, said during a media conference call. "I looked into [Aldo's] eyes, and I saw fear. It's something I expected…I don't blame the man. I was going to f*****g butcher him. Rip him limb from limb."
However, this is not the first time that Aldo has withdrawn from a title fight, having also done so ahead of bouts with Josh Grispi at UFC 125, Erik Koch at UFC 149, Frankie Edgar at UFC 153 and Mendes at UFC 176.
As a result, McGregor believes that Aldo, who he has engaged in numerous verbal battles with, should be stripped of his title after pulling out of yet another title match-up.
"I don't know if he'll be back," McGregor said. "If a man pu****s out, and he's p****d before time and time again…The [featherweight] belt should rightfully be stripped and given to its rightful owner."
