Nate Diaz told a drug tester to "f****** suck d***" as he attempted to give a urine sample ahead of his return to the octagon.
Diaz will make his final octagon bow against Khamzat Chimaev at UFC 279 on September 10 at the T-Mobile Arena in Las Vegas. It will be his curtain call after a long career with the promotion, as he plans to move on and explore other opportunities following the expiration of his contract.
Ahead of the fight, the pair are required to provide clean samples as part of the UFC's USADA drug testing programme. Diaz showed fans the process on an Instagram live stream where he showed little care despite a drug tester being present at his house. The American star lit up a joint and smoked it while offering to pass it to his friends.
