Just 24 hours prior to the United States Anti-Doping Agency (USADA) confirming that Conor McGregor tested clean for any banned substances before, during and after UFC 196, Nate Diaz’s coach accused the Dubliner of using performance enhancing drugs.

Last night US website MMAjunkie.com published the findings of the Nevada State Athletic (NSAC) Commission and USADA from their drug testing of all 24 fighters who competed at UFC 196 on March 5.
