In case you haven’t heard, Mark Hunt is quite upset with Dana White

The UFC (Ultimate Fighting Championship) is claiming to be looking out for the best interest of the former title contender. However, that doesn’t mean that Hunt agrees with it or is pleased about its latest decision regarding his career.

Hunt was set to take on Marcin Tybura in the heavyweight main event of UFC Sydney (UFC Fight Night 121) next month.

However, the promotion announced on Tuesday that “The Super Samoan” has been removed from that booking due to “medical concerns” and he will be replaced by former UFC heavyweight champion Fabricio Werdum.

Hunt decided to take to Instagram to comment on the news and obviously, it didn’t sit well with him. Thus, he sent an expletive-laden message aimed at UFC president Dana White and threatened to sue him over the news:

UFC Fight Night 121 is set to take place on Sunday, November 19th 2017 at Qudos Bank Arena in Sydney, Australia. The main card will air on FOX Sports 1 while the preliminary card will be split broadcasted on FOX Sports 1 and the promotion’s streaming service, UFC Fight Pass.

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. So it was suggested we send him to the specialist in Sydney to do a full test of his brain which he did all last week and the results came back with nothing major that he couldn’t compete with. UFC mentioned they didn’t feel comfortable because of the statements he made still and would like more tests done so Mark wasn’t able to go forward with the fight in Sydney, unfortunately.”

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 almost 20 years of professional MMA and kickboxing.

“I will probably end my life fighting,” Hunt wrote this past September. I’ve been fighting since I was a child, fighting to get out of my circumstances. I used to make $300 a week, struggling to put food on the table but I have become one of the highest-paid fighters in the world. I feel that’s destiny. This is what I’m supposed to be doing, and if I die fighting, that’s fine. I just hope that if it does happen, it will be in an honest and fair competition.

“My body is f**ked, but my mind is still here. I’ve still got my senses about me, and I know what’s right and wrong, which is the main thing. Sometimes I don’t sleep well. You can hear me starting to stutter and slur my words. My memory is not that good anymore. I’ll forget something I did yesterday, but I can remember the s**t I did years and years ago.

“That’s just the price I’ve paid – the price of being a fighter. But I’ve fought a lot of drug cheats and copped a lot of punishment from guys who were cheating, and that’s not right.”
