Mark Hunt has called for a UFC fighters' union as he steps up his attack on management following Brock Lesnar's failed doping tests.
"The way I see it, the Brock Lesnar doping thing is just another reason why we need a fighter's association," Hunt told MarkHunt.tv.
"These guys are just making up the rules as they go."
A day after learning Lesnar not only failed a drug test in the lead-up to their July 19 UFC 200 fight, but also on the day of the bout, Australia-based heavyweight Hunt said he had not been contacted by UFC management despite his aired grievances.
The 42-year-old New Zealander had already demanded a greater share of the purse from their fight, which he lost via unanimous decision, if Lesnar is confirmed to have doped.
"They say they are cleaning up the sport, yet I've risked my health two times against guys cheating since this USADA thing started," said Hunt, referring to Lesnar and his fellow American Frank Mir.
US anti-doping body USADA has administered the UFC anti-doping policy since July 2015.
Hunt beat Mir at UFC Fight Night Brisbane on March 20 and Mir was later found to have tested positive in an in-competition test.
"I was told Brock was gonna be tested when I took the fight, he comes in looking fricken juicy as hell and then I find out he's popped after the PPV (pay-per-view) has already been sold," he said.
"It's ridiculous. The fact that they haven't even bothered to make contact with me since all of this happened just proves they don't care."
After the first anti-doping violation, Lesnar provided a short statement to the AP, claiming, "We will get to the bottom of this."
The substance for which Lesnar tested positive was not disclosed, per USADA policy, and will not be until the process is concluded, unless Lesnar offers to do so.
The UFC released a statement on the second doping positive, saying they were investigating the matter.
"The UFC organisation was notified today that the US Anti-Doping Agency (USADA) has informed Brock Lesnar that his in-competition sample collection from July 9, 2016, at UFC 200, has tested positive for the same substance as his previously announced out-of-competition collection on June 28, 2016," the statement read.
"USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case."
