Mark Hunt has absolutely unloaded on Jon Jones ahead of his return to the octagon, calling him a 'steroid using rat'.
The MMA icon also took aim at the UFC for promoting him, insisting they will 'never be credible' in his eyes.
Hunt's deep-seated issues with the UFC stems back a long, long way.
Back in 2017, he filed a lawsuit against the company, claiming the UFC knew about Brock Lesnar’s use of a banned substances prior to Hunt's fight with him at UFC 200.
Since then, the New Zealand-born adopted Aussie has taken any chance he can to hit out at the UFC.
But these latest comments, right here, might be his most damning to date – and it revolves around arguably the UFC's biggest star who, as we all know, has a history of dabbling in PEDs.
In a post on Facebook, Hunt wrote: "Sick of this rat company up on my feed all they do is promote steroid using rats like this loser listen up it’s the world heavyweight title of a worthless rubbish belt worth nothing u got a steroid using rodent who runs over pregnant women and hides under the octagon when USADA is trying to drug test this rodent ufc = joke belt the only thing u are the world champion of is being exploited that’s why @ufc will never be credible because they have rodents like this being considered GOAT."
People flocked to the comments section to have their say – some throwing their support behind the former heavyweight title contender.
One person replied: "Steroids ruin the sport for sure."
While another added: "Respect to you Hunt, you are a legend of the sport and I remember watching you in the K1 and Pride days."
As a third said: "Never been a fan of Jones but I’m big fan of you Mark “Super Samoan” Hunt."
Meanwhile, others weren't entirely onboard with Hunt's claims, reminding the 48-year-old of his other past employers.
The comment with the highest amount of likes read: "Salty AF... K1 & Pride had juice users when you were competing but never heard you call out those promoters in the past, Mark... Juice or no juice, Jon is a better fighter than you."
Someone else added: "I get what your saying mark but never forget you fought how many times for pride the biggest steroid and fight fixing show of all time."
Hunt hasn't fought in a mixed martial arts bout since 2018.
He recently made the transition into boxing, losing to ex-NRL star Paul Gallen before going on to defeat former world champion Sonny Bill Williams.
