Retired mixed martial arts (MMA) fighter Cung Le ended his career on a sour note, testing positive for elevated levels of human growth hormone in a drug test overseen by the UFC following his bout against Michael Bisping on Aug. 23, 2014 in Macau.

But the way he tells the story, Le seems to think that unpleasantness was entirely the fault of UFC president Dana White and CEO Lorenzo Fertitta.

Speaking with Nate Quarry on his "Round X Round" podcast, the Vietnamese-American fighter said UFC repeatedly forced him into situations where he had to fight injured and then "botched" a drug test he didn't really fail.

In 2012, following his bout against Patrick Cote at UFC 148, Le says his foot was so badly injured he was forced to move about in a "walking boot." He reportedly ran into Dana White at UFC on Fuel TV: Munoz vs. Weidman, where he told him he couldn't fight in Macau.

"Two weeks after that Dan Henderson fought Lyoto Machida[sic]. I was in Los Angeles and they told me to meet them after the fight. I told them the doctor still hadn't cleared me. 'Hasn't cleared you? You've got to step up for the company.' I told them I couldn't get the doctor to give me a notice. I don't think they can do that. I told them hopefully I would be cleared in a week. Dana says, 'OK. You've got to let me know right away.' That night I'm driving and my phone blows up. Dana had announced my fight with Rich Franklin in Macau."

Le, 43, also complained that his gig as a host on "The Ultimate Fighter: China" earned him less than "a tenth" what he would have earned in the form of a fight purse.

When Le returned to the Octagon in Macau against Bisping following a two year absence and popped for human growth hormone, he claims UFC pressured him into admission of guilt for using PEDs. This was despite the fact that Dr. Don Catlin, an expert in performance enhancing drugs, suggested Le's HGH levels were lower than the expected post-exercise reference range for an athlete delivering a sample after strenuous activity.

"Dana called me and tells me if I just admit it, it'll be easier. The public would forgive me more. 'Look at the pitcher from the New York Giants[sic], he got busted for something.' Dana was saying it's easier just to admit it. I just didn't want to talk to him anymore. Had to hang up. He might as well have just sent some thugs to my house to strong-arm me or something. It's just ridiculous. Sometimes you get the s**t end of the stick and they just happen to be the s**t."

Harsh.

But to add some context to this whole thing, both Le and Quarry, along with Jon Fitch, are plaintiffs in a class-action antitrust lawsuit against Zuffa, accusing the UFC parent company of violating the Sherman Antitrust Act.

The suit accuses the company of illegally maintaining monopoly and monopsony power by "systematically eliminating competition from rival promoters, artificially suppressing fighters' earnings from bouts and merchandising and marketing activities through restrictive contracting and other exclusionary practices."

Despite this, when Le officially announced his retirement from the sport earlier this year in January, Lorenzo Fertitta issued a statement praising him as "one of the most exciting middleweights to step foot in the Octagon" and wishing him the best in his future endeavours.

No word yet on what he thinks about Le's words on Quarry's podcast.
