Check out who was burning up and who was chilling out in this week's hot or not list.
Hot -- "The Ultimate Fighter:" It's been a long road for the reality show that helped launch the UFC into the company it is today. Until this season, there hadn't been many memorable moments or fighters in year, but an updated show changed that.
Not -- Matt Mitrione: You think he'd be on the hot list after his fast knockout win last weekend, but his mouth has pushed him to the not list. Mitrione went on the MMA Hour on Monday and ripped trans fighter Fallon Fox as a "sociopath" and "freak," which led to Mitrione's suspension.
Hot -- Conor McGregor: After winning over Marcus Brimage at UFC on Fuel 9 last weekend with a Knockout of the Night win, McGregor didn't have to pick up another welfare check. Though his lobbying for a fight at UFC 159 didn't work because of injuries to both Joe Proctor and Al Iaquinta, he still made quite the jump into MMA's zeitgeist this week.
Hot -- UFC code of conduct: The UFC said that they were introducing their code of conduct in January, but Mitrione's actions tested it. You can check the complete code here, and find out what UFC CEO Lorenzo Fertitta hopes to accomplish with it.
Still taking temperature -- Uriah Hall: Saturday's TUF finale is filled with fighters who have a great opportunity. At the top of the list is Hall, who has the most hype behind him of any TUF contestant in years. Can he handle it? We'll find out Saturday night.
