The UFC has announced that former featherweight and lightweight champion Conor McGregor has accepted an 18-month sanction for a violation of anti-doping policy. In a statement on their website, the MMA promotion said that McGregor missed three attempts by Combat Sports Anti-Doping to collect biological samples from him in 2024 on June 13, September 19, and September 20, leading to so-called "whereabouts failures".
