When can fans expect Conor McGregor to make his return to the octagon?

At UFC 168, former middleweight champion Anderson Silva sustained an injury similar to Conor McGregor's recent fracture. The Brazilian fighter had also snapped his tibia and fibula after landing a kick on Chris Weidman. It took 'The Spider' more than a year to recover from the gruesome injury and make his comeback.

"I was afraid," said Anderson Silva in an interview with ESPN. "I don't look at my leg. I don't see my leg. I just take the medicine and just sleep for two days."

Going by Anderson Silva's recovery timeline, fans can expect 'Mystic Mac' to return next year. Dr. Brian Sutterer, a resident physician at the Mayo Clinic, also concurs that Conor McGregor will be able to revamp his athletic career post-recovery.

"Bones heal really well but it's this other type of stuff that can sometimes make the recovery a lot more difficult. Nevertheless, I'm glad to hear his surgery went well. There is no reason to think that his career is over. These generally heal just fine. We saw Anderson Silva come back...lot of examples of pro-athletes who've had pretty gnalry looking tibia fractures who've still been able to return to their sport," said Brian Sutterer.
