UFC star Conor McGregor has not been subject to a drug test since the third quarter of last year.
As part of the UFC's anti-doping policy which was implemented in 2015, all fighters are subject to random drug tests 365 days a year.
Whereabouts information is submitted to the United States Anti-Doping Agency [USADA] by the fighters, which allows the anti-doping agency to locate them for out-of-competition testing.
