Controversial UFC star Conor McGregor has been suspended for 18 months by the UFC anti-doping program Combat Sports Anti-Doping (CSAD) for violating the UFC’s Anti-Doping Policy.
In its announcement, CSAD said the Irish fighter missed three attempted biological sample collections during a 12-month period in 2024 and that constituted a violation of anti-doping policy.
The suspension began retroactively on Sept. 20, 2024 and will run through March 20, 2026.

The missed testing dates occurred on June 13, Sept. 19 and Sept. 20, 2024, and were all classified by the CSAD as “Whereabouts Failures,” though the announcement noted that McGregor had been recovering from an injury and was not in any fight preparation. McGregor last fought in July 2021.
“McGregor fully cooperated with CSAD’s investigation, accepted responsibility, and provided detailed information that CSAD determined contributed to the missed tests,” the announcement read.
