McGregor Rehab Under Scrutiny Over Alleged Banned-Substance Use
A New York Times report alleges Conor McGregor used powerful, banned drugs to recover from his 2021 leg injury; his surgeon says he did not prescribe them but supported a therapeutic-use exemption that was not granted. McGregor left USADA’s testing pool during recovery and later faced a retroactive 18-month suspension for missed tests. He is now set to headline UFC 329 against Max Holloway, with experts noting little evidence that banned substances aid bone healing and highlighting the regulatory controversy surrounding his case.
