Introduction
UFC 264: Poirier vs. McGregor 3 took place on Saturday, July 10, 2021 at the T-Mobile Arena in Las Vegas. It was the most anticipated trilogy bout in modern UFC history, the second McGregor PPV of 2021, and the night the rivalry ended in the most graphic injury of the year. The card produced an estimated 1.8 million pay-per-view buys.
At the very end of round one, McGregor's left tibia and fibula snapped as he stepped back off the rear leg. The bone gave way under the weight transfer; he fell forward, clutching his shin. Referee Herb Dean waved the fight off at the bell. Dustin Poirier was awarded the TKO via doctor stoppage, completing a 2-1 series win over a six-and-a-half-year rivalry.
The co-main saw Gilbert Burns outpoint Stephen Thompson over three rounds in a competitive welterweight bout, confirming Burns's place as a top-three contender after his UFC 258 title-fight loss.

The Build-Up
The trilogy bout was inevitable after UFC 257. Poirier had broken McGregor down with calf kicks in January 2021 and stopped him in round two — the first MMA KO loss of McGregor's career. McGregor spent the six months between fights publicly demanding the rematch. The UFC obliged.
The pre-fight cycle was the most contentious McGregor had been in for years. He insulted Poirier's wife at the pre-fight press conference, threw a kick during the staredown, and openly cursed at his rival from the dais. Poirier remained measured. The full ticket-buying public packed T-Mobile Arena for the highest UFC gate in history.
Main Event: Poirier vs. McGregor 3
McGregor came out aggressive, throwing combinations to the head and openly trash-talking Poirier in the cage. Poirier weathered the storm, clinched, and dragged McGregor to the canvas. From half-guard, Poirier landed sustained elbows for over a minute. McGregor's cuts opened along the brow line.
At 4:59 of round one, with one second left, McGregor stepped back off his left leg to throw a counter — and the tibia broke. The bone gave way under the weight transfer; the leg buckled at the ankle. McGregor fell forward, screaming.
The round ended. The cage-side physician confirmed a compound fracture of the tibia and fibula. The fight was waved off; Poirier was awarded the TKO (doctor stoppage). McGregor underwent emergency surgery the next day. The compound fracture required a titanium rod and over 17 months of rehabilitation.
Co-Main Event: Burns vs. Thompson
Gilbert Burns fought a three-round welterweight chess match. After his UFC 258 title-fight loss, Burns needed a win to stay in the upper tier of welterweight contention. He used his wrestling to chain takedowns through every round, landed sustained ground-and-pound, and avoided the long-range exchanges Thompson wanted. Final scorecards: 29-28, 29-28, 29-28.

Legacy & Impact
UFC 264 is remembered as the night a championship-level rivalry ended in the most violent imaginable way — not by knockout, but by accumulated leg damage that culminated in a bone snapping under a routine weight transfer. The trilogy was over, and Conor McGregor's career was suspended indefinitely.
For Dustin Poirier, the win locked in his 2-1 series victory and positioned him for one more title shot. He fought Charles Oliveira for the lightweight title at UFC 269 in December 2021 (third-round rear-naked choke loss), then won the BMF belt against Justin Gaethje at UFC 291 in July 2023. He retired from active competition in 2024.
For McGregor, the injury was the formal turning point of his late-career arc. He returned for one fight at UFC 309 in November 2024 — a unanimous-decision loss to Michael Chandler. The Notorious era of dominance had ended at UFC 264.
FAQ

Compound fracture of the tibia and fibula at the very end of round one.

The official medical assessment was an acute traumatic fracture.
Did McGregor and Poirier ever fight again?

Over three years. McGregor underwent emergency surgery the day after the fight, including the insertion of a titanium rod in the tibia. The rehabilitation took 17 months. He did not fight again until UFC 309 in November 2024 — a unanimous-decision loss to Michael Chandler.
Why was UFC 264 the highest UFC gate in history?
The $10.1 million gate reflected three factors: full-capacity T-Mobile Arena (20,000+ seats); premium pricing for McGregor main events; and a robust secondary ticket market on resale platforms. The figure was eventually surpassed by UFC 285 in 2023.
Did Poirier ever win a UFC title?
Not an undisputed UFC lightweight title. Poirier held the interim UFC lightweight title in 2019 (defeating Max Holloway at UFC 236) but lost the unification bout to Khabib at UFC 242. He won the BMF belt against Justin Gaethje at UFC 291 in July 2023. He retired from active competition in 2024.
How does UFC 264 compare to UFC 263?
UFC 264 drew approximately 1.8 million PPV buys versus UFC 263 (600,000) four weeks earlier — a tripling of the previous card. The gap reflected the unique commercial magnetism of Conor McGregor main events.
