Dustin Poirier has launched a scathing attack on Nate Diaz by accusing him of pulling out of their fight and casting doubt over his upcoming clash with Jorge Masvidal.
Diaz, 34, made his sensational UFC return in August with a victory over Anthony Pettis and is slated to headline UFC 244 next month against Masvidal for the BMF title.
But the American UFC star stunned fans by saying that he would not compete at UFC 244 after suggesting that he failed a doping test.
Poirier, who has been in hospital over a persistent hip injury, posted two videos on Twitter from his hospital bed as he called Diaz a "b***h."
The 30-year-old former interim UFC lightweight champ said: "Talking all that s**t about steroids. F**k you, Nate.
"Pulled out? You pulled out of my fight, too. You're a b***h. Fake a**e gangster."
Diaz was scheduled to face the 'Diamond' in 2018 after his hiatus from UFC, but Poirier was sidelined through injury and UFC president Dana White would later confirm that the fight was off.
The 'Stockton Slugger' denied any wrongdoing in his lengthy Twitter statement by insisting that he only takes "Whole Food or natural food supplements."
Diaz said in his statement: "I'm not gonna make it out to NYC for fight week next week because they say I tested with elevated levels that they say might be from some tainted supplements.
"I call false on that cause I only take Whole Food or natural food supplements. I don't even eat meat. So until UFC, Usada or whoever is F*****G with me Fixes it, I won't be competing.
"I'm not gonna play their game and try and hide it or keep quiet, as they suggested.
"I'm not gonna have my name as tainted as a cheater like these other motherf*****s who keep quiet until after the fight just so they can get paid. f****n cheaters."
Conor McGregor, who fought Diaz twice, wasted no time in reacting to the news before deleting the tweet about his fierce rival.
Meanwhile, Masvidal has leapt to Diaz's defence and insisted that 'he will see him' on 2nd November for their UFC 244 clash.
According to ESPN's Ariel Helwani, Diaz has not been provisionally suspended and there is 'increased optimism' that the fight won't be cancelled.
