Conor McGregor tops list of clean UFC fighters tested the most by USADA

No UFC fighter has had more samples collected and analysed by the United States Anti-Doping Agency without a single issue than Conor McGregor

This summer marks the fourth anniversary of the UFC's partnership with USADA and while there have been several examples of high-profile fighters failing tests since 2015, Jeff Novitzky wanted to celebrate those who have consistently provided clean samples. Novitzky, the UFC's Vice President of Athlete Health and Performance, has revealed the most-tested fighters who have never encountered a problem with a sample. Thanks to his extensive testing ahead of his professional boxing debut against Floyd Mayweather, McGregor tops the list with 49 samples. https://twitter.com/JeffNovitzkyUFC/status/1113961443387269121 UFC heavyweight champion Daniel Cormier follows close behind with 45 samples without issue while the likes of Rafael dos Anjos, Holly Holm, Stipe Miocic, Robbie Lawler, Amanda Nunes, Jose Aldo and Tyron Woodley complete the top nine. Being known as a clean fighter is a badge of honour for most and McGregor has previously documented his enjoyable experiences with USADA's testers. https://www.youtube.com/watch?v=fKBVj9XZxqk In the run-up to his rematch with Nate Diaz at UFC 202, McGregor published the above video of a tester showing up to take a sample just as 'The Notorious' was leaving for a training session in Las Vegas.
