Jon "Bones" Jones Talks about His Hatred for Toy UFC Belts

This moment may not be considered controversial by some, but it deserves to be on the list for the kind of roar it received from fans. Jon Jones stated in an interview that he hates the plastic UFC belts sold in stores because people are able to get those without having to put it any effort.
This simple statement ended up damaging Jones’s image as fans started looking at him more as a loudmouth than a friendly fighter.

Dana White Uses Anti Gay Language

UFC’s president Dana White received an angry reaction from the Gay and Lesbian Alliance Against Defamation (GLAAD) when he used foul language against Loretta Hunt, an MMA journalist, and an unknown source. This was as a response to the criticism UFC received for the treatment of managers.
Dana White, taking it a step further, ended up including anti-gay slur ticking off many people the wrong way. The GLAAD thought that the president of a chief sports organization should not indulge in such acts. This not only brought bad publicity to UFC but also tarnished Dana White’s image who had to apologize.

Kimbo Slice-Seth Petruzelli Post Fight Fiasco

The original card for EliteXC was Kimbo Slice vs. Ken Shamrock, but the later had to back out as he got injured on the day of the fight and was replaced by Seth Petruzelli. This put Seth, a lightweight, against Kimbo Slice, a heavyweight and resulted in one of the most controversial fights in history.
Slice got knocked out by an off-balance jab by Petruzelli at the 14 seconds mark. This resulted in EliteXC not only losing one of its most marketable stars but the aftermath resulted in more damage.
Petruzelli confessed in a radio interview that the promoters persuaded him to just stand with Slice instead of taking him down. His comments attracted the Florida Department of Business and Professional Regulation and brought bad name to the organization and Kimbo Slice, even though no evidence of wrongdoing was found.

Chael Sonnen’s Trial

Chael Sonnen vs. Anderson Silva was considered a predictable match until Sonnen ended up dominating Silva for the better part of the match. He, however, ended up losing thanks to a triangle choke but received a huge round of applause for his performance.
Nonetheless, the main news was not his performance but what followed. Eventually it was announced that Sonnen's testosterone levels were above the normal level as per his post-fight test. This resulted in Sonnen’s suspension. He appealed against it and was given a slap on the wrist.
Things got worse when the man got in more controversy (money laundering, etc.) later on losing a major portion of his fans.
