The decision could have something to do with an article Hunt wrote for Playersvoice.com, in which he laid out his health problems, and discussed other hot topics such as doping and fighter pay.
If you recall, Hunt recently wrote a passionate testimonial for the Players Voice, and he detailed some of the health problems that have been plaguing him due to his nearly 20 years of professional MMA and kickboxing.
It's interesting to see Hunt refer to the Player's Voice article as an "interview" as he was quoted as author on the story.
UFC officials announced the news on Tuesday. "I've still got my senses about me and I know what's right and wrong, which is the main thing", Hunt wrote in a piece for the Players Voice.
Hunt is adamant he is still able to fight, saying he passed all his medicals before being pulled from the November card in Sydney. The truth is the legal case I have filed has caused me to be withdrawn.
There were three Instagram posts in total, with the last one the most measured of the trio.
'Sometimes I don't sleep well. I'll forget something I did yesterday, but I can remember the s**t I did years and years ago.
The loss was later overturned to a no-contest after Lesnar tested positive to a banned substance.
Hunt's manager also released this statement: "UFC mentioned they were concerned with Mark's health based on his previous interview with mentioning slight health issues".
But a furious Hunt insists he has been cleared to fight by doctors and believes the real reason behind his removal is his current legal battle against the UFC, president Dana White and former opponent Brock Lesnar.
"I think Mark Hunt deserves to be more a part of his children's life and hopefully his grandchildren, and not be "punchy" which is a road he's headed down if he continues to take this kind of punishment".
"The organization will require that Hunt undergo further testing and evaluations prior to competing in any future UFC bout", an unnamed UFC official told Australia's Daily Telegraph newspaper.
