Qileng Aori is set to compete in his second UFC fight as he takes on Cody Durden at UFC Vegas 43. ‘The Mongolian Murder' is hoping to bounce back from a debut loss to Jeff Molina back in April.

Qileng Aori sports a unique nickname in ‘The Mongolian Murder' and it's not for a regular reason. It would seem the UFC fighter is from Mongolia and he ‘murders' his opponents in the cage, so the nickname is obvious… wrong!

ClutchPoints spoke to Qileng Aori ahead of UFC Vegas 43 and found out the origins of his nickname. The name was bestowed upon him by Dean Amasinger, the President of the UFC Performance Institute in Shanghai.

“This nickname was given to me by the head coach of the UFC PI Shanghai, Dean Amasinger,” Aori told ClutchPoints. “When I had just arrived at the PI and started training there. I didn't know how to spare properly. I had no mercy for my sparring opponents. So all of them were getting hurt. Bruises on their faces and cuts on their faces after they sparred with me. That's why coach Dean gave me this nickname: Murderer, Mongolian Murder.”

It is an unwritten rule in MMA that UFC fighters are to respect their training partners. The goal is for everyone to get better without getting injured or hurt.

Qileng Aori has learned from that rule and is much nicer to his sparring partners now. He won't be looking to be nice to Cody Durden though when he faces him on the prelims of UFC Vegas 43.
