Dustin Poirier’s leg break in 2021 still casts a shadow over UFC 329, where Conor McGregor makes his long‑awaited return against Max Holloway on 29 Sep 2026 at T‑Mobile Arena. The injury, inflicted by Poirier five years ago, was McGregor’s second defeat to the former lightweight champion and remains a key storyline for fans and oddsmakers.

How did Poirier’s injury affect McGregor’s career?

The broken leg occurred during their June 2021 bout, ending McGregor’s momentum and triggering a three‑fight losing streak that includes a loss to Khabib Nurmagomedov in 2018. Poirier’s knockout not only sidelined McGregor for over a year but also forced the Irish star to rebuild his standing in the welterweight division. The physical trauma and subsequent rehab have been cited by analysts as reasons for McGregor’s cautious approach heading into the Holloway fight.

Why is the Poirier‑McGregor history relevant to UFC 329 betting?

Oddsmakers on DraftKings list McGregor as a -250 favorite, yet the lingering narrative of Poirier’s devastating strike adds uncertainty. Bettors recall Poirier’s ability to end fights early—he secured a KO in the first round of their 2021 clash—prompting many to hedge with over/under rounds bets. The event’s hype, amplified by the injury backstory, is driving higher handle volumes than typical Fight Week cards.

What does the Poirier connection mean for the main event?

Max Holloway, coming off a decision loss to Charles Oliveira that cost him the BMF title, faces a McGregor who is still proving he can compete after a severe leg injury. Holloway’s camp notes the psychological edge McGregor may carry, remembering the pain of Poirier’s strike. Meanwhile, McGregor’s team emphasizes his improved conditioning, arguing the broken leg is a closed chapter. The contrast sets up a narrative clash as much as a technical showdown.

How might Poirier’s legacy influence future match‑ups?

If McGregor wins, the Poirier‑McGregor rivalry could be revisited, possibly sparking a third encounter. Poirier, now a veteran with a 28‑8 record, remains a top contender in the lightweight division, and his ability to finish fights quickly keeps him in conversation for headline bouts. The UFC’s matchmaking committee will likely weigh the marketability of a Poirier‑McGregor sequel against other emerging stars.

What are the odds for the co‑main event?

Paddy Pimblett vs. Benoit Saint‑Denis is listed at -135 for Saint‑Denis on DraftKings, reflecting his recent four‑win streak after two 2024 defeats. The fight offers a contrasting storyline to the main event’s injury narrative, giving bettors a chance to diversify their tickets.

The Poirier‑McGregor injury remains a talking point as UFC 329 approaches, reminding fans that a single strike can reshape careers and betting markets alike.
