What’s Next for Conor McGregor? Should He Retire After UFC 329?

Conor McGregor’s UFC 329 comeback lasted just 69 seconds before another devastating injury left his fighting future hanging in the balance. After suffering a serious knee injury against Max Holloway, the biggest question is no longer when McGregor will fight again, but whether the former two-division champion should retire from mixed martial arts altogether.

Another Cruel Setback

Unfortunately for McGregor, this is becoming a familiar story.

Since 2021, his career has been defined more by injuries than victories.

His trilogy fight against Dustin Poirier ended with a horrific broken leg. A scheduled comeback against Michael Chandler never materialised after he suffered a broken toe. After serving an anti-doping suspension that expired earlier this year, UFC 329 was supposed to mark the beginning of one final run toward championship contention.

Instead, another catastrophic injury has left him facing surgery and yet another lengthy rehabilitation.

McGregor confirmed after the fight that he will undergo surgery but insisted he intends to recover and fulfil the final bout on his current UFC contract.

Time Is No Longer On His Side

McGregor turns 38 this week. For most fighters, that is already an age where physical decline becomes increasingly difficult to overcome.

For someone who has spent much of the past five years recovering from major injuries rather than actively competing, the challenge is even greater.

Elite MMA is unforgiving.

Reaction time slows.

Recovery takes longer.

Training camps become harder on the body.

McGregor has now suffered two career-threatening lower-body injuries in the space of five years, raising understandable concerns about whether his body can still withstand the demands of mixed martial arts.

There Is Nothing Left To Prove

Few fighters have achieved what McGregor has.

He became the UFC’s first simultaneous two-division champion.

He transformed the UFC into a global entertainment powerhouse.

He headlined some of the biggest pay-per-view events in combat sports history and became the highest-paid fighter of his generation.

His legacy was secured long before UFC 329.

Whether fans love him or hate him, McGregor changed mixed martial arts forever.

Very few athletes leave behind that kind of impact.

The Competitive Fire Still Burns

The biggest obstacle to retirement may simply be McGregor himself. Throughout his career, he has thrived on proving doubters wrong.

His statement after UFC 329 suggested he has no intention of ending his career this way. Instead, he vowed to recover from surgery and return for one final fight before walking away from the sport.

That determination has always been one of his defining qualities. The question is whether desire alone can overcome the realities of age and repeated injuries.

Could Boxing Be The Answer?

If McGregor remains determined to compete, perhaps mixed martial arts is no longer the right arena.

Several figures within the sport have suggested boxing may now represent a safer and more realistic option. The reduced emphasis on kicking, wrestling and explosive grappling places significantly less strain on the knees and lower body while still offering the blockbuster paydays McGregor commands.

A lucrative crossover bout could allow him to end his combat sports career on his own terms without enduring another gruelling MMA training camp.

The Verdict

Emotionally, every fight fan wants to see Conor McGregor return one last time. The sport has always been more exciting when “The Notorious” was competing.

But logic points in a different direction.

At 37, with multiple major injuries, years away from consistent competition and another long rehabilitation ahead, the chances of McGregor returning as the fighter who once dismantled José Aldo, Eddie Alvarez and Chad Mendes appear increasingly slim.

If he honours his promise and returns for one final UFC appearance, it should be exactly that: a farewell.

Because greatness is not measured by how long you fight, it is measured by what you achieved when you were at your best.

And at his best, Conor McGregor wasn’t just a champion. He was one of the biggest stars combat sports has ever produced.
