Conor McGregor Suffered ACL And Meniscus Injury At UFC 329

For the first time in five years, Conor McGregor stepped foot in the Octagon to compete in a MMA fight at UFC 329 against Max Holloway.

The fight lasted all of 69 seconds as McGregor suffered an injury attempting a jumping switch kick immediately as the fight began. He tried to continue, but couldn’t put any pressure on his leg and the fight was called off.

On social media, McGregor revealed he suffered an ACL and meniscus injury in the fight, but hopes to return next year.

“Update: It was acl and meniscus. It is the same injury as the first Holloway fight, only this time the opposite leg. Quite shocking. I returned to competition within 9 months to fight Diego Brandao back then. With today’s regenerative medicine advancements and improved training methods it is well within my realm to return by next summer. I am walking without a crutch. I done leg extension machine work the other day to no issue. So I can walk without aid, and activate my quad under resistance. All very positive. I am maximum discipline and have maintained it fully since the bout. I wonder was I saved from something worse here. I believe so. I would have attended the after party as “the man” and who knows then. I believe I was saved,” he wrote.
