Dustin Poirier Questions Conor McGregor's Fitness and Future After UFC 329 Injury

Poirier said McGregor looked bloated and suggested an unhealthy lifestyle may have contributed to his condition, noting changes in his facial appearance and overall shape as evidence of potential lifestyle issues.
Poirier criticized McGregor's decision to open UFC 329 with a jumping switch kick, saying he doesn’t know whose game plan that was and questioning the strategy that led to the early knee injury.
Poirier warned that if McGregor sustained a torn ACL or similar serious knee injury, it could mean a prolonged layoff and potentially end his fighting career.
Despite years of rivalry, Poirier expressed concern for McGregor's personal reforms and life off the cage, hoping the tumult of UFC 329 won't derail his strides toward healthier behavior and family life.
Conor McGregor's long-awaited UFC 329 comeback lasted less than a round before a knee injury — reportedly a torn ACL — ended his night and cast serious doubt on his future in the sport. Newsweek reported that McGregor blew out his knee during an early jumping switch kick, leading to a referee stoppage and a TKO loss to Max Holloway.
In the aftermath, former rival Dustin Poirier held nothing back. He called McGregor a "dirtbag," questioned his conditioning, and raised the possibility that McGregor's career could be over — while also saying he hopes McGregor gets healthy and stays on track personally.
Poirier did not mince words about McGregor's physical shape heading into UFC 329. He said McGregor looked bloated and pointed to visible changes in his face and body as signs of an unhealthy lifestyle. According to MMA Junkie, Poirier suggested McGregor's habits off the mat may have hurt him inside the cage.
Poirier also questioned the strategy McGregor used to open the fight. "I don't know whose game plan that was," he said, referring to the jumping switch kick that caused the knee injury. Opening a comeback fight with such a risky move, Poirier argued, showed poor preparation and judgment — not the kind of smart fighting McGregor once built his name on.
The injury may be more than a short-term setback. Newsweek reported the knee damage is consistent with a torn ACL. That kind of injury typically requires surgery and at least 9 to 12 months of recovery. For a fighter already in his mid-30s with a long history of injuries, that timeline is brutal.
Poirier warned bluntly that a serious ACL tear could end McGregor's fighting career for good. He added that if McGregor does heal, he'd be ready to fight him again at 170 pounds. But Poirier made clear he sees a real chance McGregor never returns to the octagon.
After the stoppage, some fans and commentators online suggested McGregor may have quit or was already hurt before the fight began. Poirier rejected that idea. He said McGregor is not a quitter and that the knee injury was real. According to Yahoo Sports, Poirier defended McGregor on that specific point even while criticizing him on nearly everything else.
It was a rare moment of fairness in an otherwise sharp critique. Poirier seemed to draw a line between what he sees as McGregor's lifestyle failures and his actual toughness as a competitor. In Poirier's view, the problems started long before the first bell rang.
Despite years of bad blood, Poirier said he is genuinely concerned about McGregor as a person. He expressed worry that the chaos surrounding UFC 329 could undo progress McGregor had reportedly made toward a healthier personal life and stronger family bonds. According to MMA Junkie, Poirier said he hopes those changes stick regardless of what happens next in McGregor's career.
It was a surprisingly human moment from a fighter who called his rival a "dirtbag" in the same breath. Poirier summed up his feelings simply: he wants McGregor healthy, but he also wants him to keep his life in order. Whether McGregor fights again remains an open question.
