Throughout the history of the UFC, only a few actions have remained banned since the promotion's inception in 1993. At one point, even low-blows were legal. However, small joint manipulation and fish-hooking have always been against the rules despite the events being billed as "No Holds Barred."
Despite that we saw one of these rules broken tonight at UFC Fight Night: Henderson vs. Khabilov
These few twitter posts reveal how Caraway implemented the illegal tactic:

After seeing the fight between Yves Edwards and Piotr Hallmann following this bout, I have to argue this is more an officiating problem than a competitor problem. In any competition, the athletes will look for any advantage they can find. It's up to the official to keep them from gaming the system. Caraway found a way to gain an advantage here, the same as Hallmann and Edwards found a way to poke each other in the eyes later. It's referees Mario Yamasaki and Raul Porrata that failed tonight.
