Conor McGregor is officially back in the pool – the drug testing pool that is.
For the first time in 2025, McGregor has undergone drug testing, now carried out by Drug Free Sport and CSAD (Combat Sports Anti-Doping), after the UFC parted ways with USADA.
McGregor’s name turns up on the UFC’s official test history website, showing he’s been tested once this year (h/t MMA Fighting). While the date of that test is unclear, McGregor’s name was not present prior to August.
The Irish star had announced his return to the drug testing pool in late July, sharing images of his first test, which should give some context as to when it occurred. While he was tested multiple times prior to 2024’s planned fight with Michael Chandler at UFC 303, a broken toe took him out of that bout.
McGregor had not been tested in recent months, either in 2025 or late 2024. He has not fought since suffering a broken leg in the rubber match of his trilogy with Dustin Poirier in 2021.
With the announcement of the UFC event at the White House, however, the former featherweight and lightweight champion has expressed interest in returning to competition. Who his opponent might be, and whether Michael Chandler remains of interest, remains to be seen.
Conor McGregor was recently seen fighting another battle, a losing effort in his appeal of a civil trial that found him liable for allegations of sexual assault dating back to a 2018 incident in his native Ireland.
