Conor McGregor’s UFC 329 leg injury was no accident—Dustin Poirier just called it out as a ‘career-altering moment’ in a blunt interview. The UFC lightweight legend’s fight against Poirier on 14 November 2020 ended in a brutal first-round stoppage, but Poirier now claims McGregor’s injury wasn’t just bad luck. It was a turning point that reshaped the division.

What happened at UFC 329? McGregor entered the **UFC 329** bout as the undisputed lightweight champion, but his leg injury—sustained in training—forced him into a fight he wasn’t fully prepared for. Poirier, then 30, dominated the early rounds, landing a devastating knee to McGregor’s thigh before finishing him with ground-and-pound. The stoppage came at **1:23** of the first round, a rare defeat for McGregor.

Why Poirier’s take matters now In a recent interview, Poirier told reporters that McGregor’s injury wasn’t just a setback—it was a **career-altering moment**. ‘He came back from that, but it changed him,’ Poirier said. ‘You could see it in his movement after that.’ The comment stings because McGregor has since struggled with mobility issues, raising questions about whether his prime was truly over by **UFC 329**—or if the injury accelerated his decline.

What’s next for McGregor’s legacy? Poirier’s words add fuel to the debate over whether McGregor’s best years were behind him by **UFC 329**.
