Sean O’Malley Rips 'Drug Addict' Conor McGregor: He Isn’t in Anyone’s GOAT Talk

Sean O'Malley’s went off on Conor McGregor after the Irish star mocked at the bantamweight champion’s explanation for failing a drug test.

O’Malley has tested positive for the banned substance ostarine more than once in his career. The most recent instance occurred in 2019, which led to a suspension. However, O’Malley has consistently denied having used PEDs, claiming the trace amounts found in his sample must have been due to tainted supplements.

While O’Malley couldn’t pin down the supplements that could have contained ostarine, he has found a new potential explanation for his failed tests. O’Malley claims recent studies suggest that ostarine can be transferred through sweat, possibly through sharing garments or gear. “Sugar” believes Ostarine was transferred to him while he was training at another gym, where ostarine use by athletes was public knowledge. O’Malley believes teammates Kyler Phillips and Augusto Mendes, who both faced suspensions for the same substance, also picked up traces of it while training at the aforementioned gym.

“It was me, ‘Tanquinho’ [Augusto Mendes] and Kyler [Phillips]. All trained at the same gym, all tested [positive], all levels so f—-ing low. None of us took anything, we all swore on our lives,” O’Malley said on his YouTube channel. “And I remember asking the UFC and USADA, ‘Can it be transferred through sweat?’ And they said, ‘No, not at this time. There’s no studies that ever happened.’ Just recently studies came out, scientists, athletes, it happens. It happens on someone’s knee band. Someone was sharing a knee band and they tested for ostarine. And they tested the knee band, came back that ostarine and those kind of tainted supplements can be through sweat exchange… We know exactly who the f—k it was, we have a good idea…These guys were open about it, they were on, they took it, they take it.”

While Phillips was suspended for six months back in January 2023, Mendes never fought in the UFC after getting suspended in 2018.

O’Malley’s explanation for the failed drug test didn’t sit well with McGregor, reacted to O’Malley’s comments with a laughter emoji in a since deleted post on X.

O’Malley responded by saying he missed the McGregor of old in a scathing social miedia post. While the bantamweight champ still claims to be a fan of McGregor, he slammed the recent slump in the Irishman’s career. O’Malley also claims that “Notorious” will never be considered in the GOAT conversation even though he might be the biggest superstar in the sport’s history.

“Miss the old Conor :( you fell off bud. Still a fan tho. I actually don’t care you are 1-4 in your last 5 I’m stills excited to watch. Hope the toe is feeling better,” O’Malley wrote.

“Conor isn’t in anyone GOAT talk. Entertainment yes but skills, no. Has a really good left hand. S--t cardio. Weak Jits. Decently athletic. Mentally weak. Drug addict, needs rehab. 1-4 last 5 fights. Still fan tho. Hope toe heals up.”

McGregor was scheduled to return to the Octagon after a three-year hiatus against Michael Chandler in the main event at UFC 303 last month before pulling out due to a broken toe. Meanwhile, O’Malley is rumored to defend his bantamweight strap against Merab Dvalishvili at UFC 306 in September at the Sphere in Las Vegas.
