Conor McGregor has received an 18-month suspension under the UFC’s anti-doping policy, but he’ll be cleared to return to action in early 2026.
On Tuesday, Combat Sports Anti-Doping (CSAD) — the in-house agency that runs the UFC’s anti-doping program— announced that McGregor accepted the 18-month sanction after repeated failures to submitted testing samples as required by athletes under contract with the promotion.
“McGregor missed three attempted biological sample collections within a 12-month period
in 2024, which constitutes a violation of the UFC [anti-doping policy],” CSAD officials wrote in a press release. “UFC athletes are required to provide accurate whereabouts information at all times, so they can be contacted and submit to biological sample collections without prior warning.
“McGregor’s missed tests occurred on June 13, September 19, and September 20, 2024, and were each classified as Whereabouts Failures by CSAD under the UFC ADP.”
While each missed test counted against McGregor, CSAD officials noted that he was out of action dealing with an injury and not preparing for an upcoming fight when the samples were supposed to be collected.
“McGregor fully cooperated with CSAD’s investigation, accepted responsibility, and provided detailed information that CSAD determined contributed to the missed tests,” CSAD officials noted.
“Despite these mitigating factors, CSAD emphasizes that accurate whereabouts filings and the ability to conduct unannounced testing are essential to the success of the UFC ADP. Taking McGregor’s cooperation and circumstances into account, CSAD reduced the standard 24-month sanction for three whereabouts failures by six months. His period of ineligibility began on September 20, 2024 (the date of his third whereabouts failure) and will conclude on March 20, 2026.”
The suspension and the expiration date when McGregor is eligible to compete again won’t interfere with his planned return to action, which he has repeatedly stated comes for the UFC White House card now scheduled on June 14.
McGregor hasn’t fought since 2021 when he suffered a broken leg in a fight against Dustin Poirier. He was originally scheduled to return in 2024 for a showdown with Michael Chandler but the Irish superstar suffered a broken toe in training that forced him off the card.
After President Donald Trump announced plans to hold a UFC event at the White House in 2026, McGregor immediately said he wanted to fight on the card with hopes that he could finally settle some unfinished business with Chandler.
McGregor is still undergoing testing as part of the UFC’s anti-doping program with the former two-division champion already submitting four samples in 2025.
