After winning the UFC interim featherweight title at UFC 189 by defeating late-replacement Chad Mendes, Conor McGregor revealed he had suffered a knee injury during his training camp. Until this point, McGregor never fully revealed any details regarding the injury. That is, until now.

"Fourteen weeks before the fight I tore 80 percent of my ACL," said McGregor during a fan Q&A in his hometown of Dublin, Ireland. "I could barely walk, I could barely kick."

"I had a lot of experience coming back from that injury. I was aware of my body, I was aware of my balance. I had a good team around me. I trusted everyone that was there. That's how I perform.

"So, once again, I had a lot of adversity to overcome," McGregor continued. "But honestly, I went into that fight and I beat Chad on one leg. After going through that adversity I feel like I have gained three new legs."

McGregor previously suffered an ACL injury during his UFC Fight Night 26 bout opposite Max Holloway on Aug. 17, 2013. The Irish featherweight won that bout despite the setback via unanimous decision.

The SBG Ireland fighter is currently scheduled to fight UFC featherweight champion Jose Aldo in a bout that will unify the featherweight title. This fight will take place as the main event on Dec. 12 at UFC 194 in Las Vegas, Nevada.
