Conor McGregor’s UFC comeback may have only lasted 69 seconds, but he is still breaking records as a result.
During his five years away from the sport, McGregor actually served a suspension for missing drug tests around the time that his ill-fated fight with Michael Chandler was cancelled. As a result, there were no chances taken with his cleanliness before he came back to fighting this year.
Who would you pick for Conor McGregor to fight in his BKFC debut and why?🤔
McGregor has just one fight left in the UFC before he is free to fight wherever he wants.
Even now, UFC drug testing records show that McGregor is not only the most tested athlete on the roster in 2026, but there is nobody close to him. This is despite his last test coming around his fight with Max Holloway at UFC 329.
Conor McGregor is UFC’s most tested athlete in 2026
As UFC anti-doping records were updated this week, it was confirmed again that Conor McGregor is far and away the most tested athlete of this year. He was tested 15 times since January, with the joint second place fighters on the list only having eight.
Anthony Hernandez and Luis Dias de Assis are the second-most tested fighters, both competing twice at middleweight. Social media user Jed I Goodman compiled a list of names who have been tested, noting that 759 fighters have been tested in 2026.
Goodman also revealed that 3355 total samples have been collected this year to date, with all UFC fighters required to submit to random testing. It remains unclear when exactly McGregor’s last test was.
