UFC Fight Night 42 was mired in controversy on Saturday, with Ross Pearson losing in a massively controversial split decision to Diego Sanchez, as well as several illegal moves elsewhere.

Pearson was fighting in the co-main event of the evening against Sanchez, and looked to everyone that he'd taken each round as it went to the decision... everyone except the judges.

The final scores were 30-27 Pearson, 30-27 Sanchez, 29-28 Sanchez and the look of bemusement on Pearson's face told the entire story.

What made the decision so controversial is that Pearson knocked Sanchez down in Round Two and with how well Pearson was out striking him, it should have been an easy round to score.

The Telegraph's Gareth A Davies has revealed that Pearson has lodged an appeal with the New Mexico Athletic Commission (NMAC), although it's unlikely that he'll have the result overturned or annulled.

Only an investigation that uncovered clear rule violations or judging mistakes would see the result changed. The UFC has decided to leave it with the NMAC.

Speaking about the fight Pearson said, "That’s happened to me twice now. I’m going to have to think only about myself from now on when it comes to what city that I fight in. It’s not worth my record and my career to let this happen again."

It wasn't the only controversial fight of the night though as it emerged that Brian Caraway 'fish hooked' his opponent, Erik Perez in their Bantamweight clash.

A Twitter picture and subsequent Vine video both show Carraway with his fingers in Perez's mouth and pulling on his cheeks, a move that is banned in the UFC. Fortunately for Carraway, neither the judges nor referee were able to clearly see it.

Caraway later said he that he had apologised to Perez for the 'accidental' fish hook but it still left fight fans furious with Caraway.

He's struggled for fans before as he controversially said he'd like to beat up UFC Women's Bantamweight Ronda Rousey during his time on The Ultimate Fighter, where he was a coach for girlfriend, Miesha Tate's team.

As for the rest of the card at UFC Fight Night 41, Benson Henderson secured his first submission victory in the octagon with a rear naked choke on Rustam Khabilov in the main event and John Dodson forced a doctor's stoppage against John Moraga.

Dodson busted open Moraga's nose with a knee shot in the second round and after the round was over, the doctor stepped in. That now puts him in line for a flyweight title shot against either Demetrius Johnson or Ali Baguintov - depending on the winner of their UFC 174 clash.
