Conor McGregor calls Nate Diaz a ‘juice head’ following surprise USADA visit

Conor McGregor appears to be lobbying for a rematch with Nate Diaz — or perhaps a scrap with older brother Nick — as the former UFC lightweight and featherweight champion recently called Diaz a ‘juice head’ following his surprise USADA drug test on Friday.

“Juice head rats,” McGregor posted on Friday, possibly in reference to both Diaz brothers.

Diaz accused McGregor of using steroids prior to their welterweight clash at UFC 196, to which McGregor responded by reminding Diaz that both his teammates Gilbert Melendez and Jake Shields had tested positive for performance-enhancing drugs in the past.

“Your two teammates were on steroids. Your two boys. The scrap pack – remember that? What happened there? Did you know they were taking that stuff? Did you know they were taking that stuff?”

Neither McGregor nor Diaz have ever failed a drug test, but former Strikeforce welterweight champion Nick Diaz has tested positive for marijuana metabolites on multiple occasions. The UFC veteran actually received a longer suspension than UFC 183 opponent Anderson Silva, who tested positive for steroids (drostanolone and androsterone) in 2015.

Nick Diaz recently completed a 14-week diet and training regiment and is expected to make a comeback later this year.
