​Sean Strickland posted a provocative theory about Conor McGregor’s injury ahead of UFC 329, igniting further discussion about whether the Irishman was compromised before stepping into the Octagon. The Ultimate Fighting Championship middleweight champion weighed in on the matter after McGregor’s highly anticipated return to action at UFC 329, a bout that ended almost as soon as it began. McGregor, returning after a five-year hiatus, faced Max Holloway and saw his comeback cut short when his right knee gave way on the very first kick he threw, resulting in a stoppage loss just over a minute into the opening round.
Strickland has been cautious not to jump to conclusions, but he floated a controversial possibility: could McGregor’s injury have been influenced by long-term steroid use? In a series of posts on X, Strickland claimed that he has witnessed several steroid users experience a gradual fragility in their bodies over time. “I’m not saying this is it… but every homie I have that has done steroids for too long their bodies become so fragile,” he wrote. “I’m not saying that’s why but… it does weaken everything.” He clarified that his remarks were speculative, yet his comments added to the ongoing debate about whether McGregor’s knee issue was something pre-existing or a consequence of other factors.
The discourse surrounding McGregor’s health ahead of UFC 329 has been heated and multifaceted. Some observers pointed to the broadcast footage that showed McGregor wince and stumble slightly as he removed his shoes before entering the arena, fueling questions about possible pre-fight injury. Yet Strickland underscored his belief that a genuine injury would likely prompt an athlete to protect the injured area in the lead-up to a contest. “That’s what I’m saying… if you’re injured you’re protecting your injury to make it through the fight,” he wrote in a subsequent post, adding, “No. He wouldn’t have sent a kick like that if he was hurt. I know from experience.”
McGregor (22-7) remains one of the most scrutinized athletes in the UFC in 2026, a reflection of his long and storied career. The Irish superstar had spent time outside the UFC’s testing pool while he recovered from a leg injury sustained in his trilogy loss to Dustin Poirier in 2021. The broader testing narrative surrounding McGregor’s return is not new; he faced earlier scrutiny over his drug testing protocol as UFC leaders navigated a renewed relationship with USADA. In 2024, reports indicated tensions between the UFC and its former anti-doping partner, USADA, centered on the agency’s role in McGregor’s testing regime during a period when his return to competition was anticipated for the 2023-2024 window. Those developments have contributed to a broader conversation about how testing and injury narratives intersect when a high-profile figure makes a comeback.
As fans and analysts debate whether injury or preexisting conditions shaped McGregor’s UFC 329 performance, Strickland’s remarks have intensified the online dialogue about steroids, fragility, and athletic longevity in combat sports. Whether one accepts his hypothesis or critiques it as speculation, the exchange adds another layer to the ongoing scrutiny of McGregor’s health status and the factors surrounding his highly anticipated return to the Octagon.
