Conor McGregor is still not fighting, but he is showing up in the anti-doping numbers
Conor McGregor has not made the walk in years, yet his name keeps forcing its way back into the conversation. This time it is not because of a callout, a press conference, or another vague promise about a comeback. It is because the anti-doping test history numbers for 2026 now show McGregor sitting at the top of the list for test sessions.
That immediately catches attention for one simple reason: inactive fighters do not usually dominate this kind of stat unless there is still real movement behind the scenes. It does not automatically mean a fight is booked, and it definitely does not prove a return is imminent. But when the most tested fighter in the pool is also the biggest absent star in the sport, people are obviously going to connect dots.

The Dustin Poirier loss still hangs over everything
McGregor’s last fight remains UFC 264: Poirier vs. McGregor 3, where Dustin Poirier vs. Conor McGregor ended in ugly fashion with the broken leg stoppage. That matters because it was not just another defeat. It froze his entire competitive timeline. Since then, every comeback conversation has had the same question sitting underneath it: what does McGregor actually look like now?
That is why the testing number matters more than it normally would. Fighters can talk all year. Testing is different. Testing suggests maintenance, eligibility, and at the very least some level of seriousness about staying in the system.
What this really means right now
No, this is not confirmation that McGregor is definitely returning next month. But it does say something important: he is still active enough in the regulatory sense to keep the door open. And for a fighter this famous, that alone becomes news.
Until he is officially booked, skepticism is fair. But if you were looking for one small, concrete sign that UFC comeback talk around McGregor is not completely dead, this is probably it.
