Conor McGregor has been tested more often than any other UFC fighter in 2026, according to recent USADA data. The former two-division champion remains in the testing pool even though he has not fought since 2021.
USADA testing and fighter status
USADA continues to administer regular, random drug tests to McGregor because he is still on the UFC roster. Fighters under contract must stay in the testing pool and be available for out-of-competition tests, even during long breaks from fighting.
The testing frequency can change based on several factors, such as an athlete’s profile and past competitive history. The 2026 data show McGregor received more tests than any other UFC athlete that year, and he stayed compliant with the testing program.
Last fight and injury
McGregor has not competed since his loss to Dustin Poirier at UFC 264 in July 2021. That fight ended with McGregor suffering a broken leg. The injury and the loss have kept him out of the octagon ever since.
Because McGregor remains an active roster member, he must continue to follow all USADA rules to keep his eligibility to compete. Staying in the testing pool is part of that process.

| Conor McGregor | Lost to Dustin Poirier (UFC 264, July 2021) — suffered a broken leg |
| Dustin Poirier | Defeated Conor McGregor (UFC 264, July 2021) |
Return talk and what comes next
McGregor has spoken often about a possible return to the UFC, but he has not named a date or an opponent. Any comeback will depend on his recovery, training, and continued compliance with USADA rules.
The recent testing pattern shows he is keeping his eligibility intact. That leaves the door open for a future fight if McGregor and the UFC decide to move forward.
For now, McGregor remains a tested, active roster member who is preparing from outside the cage. USADA testing keeps him ready for competition should plans be announced.
