Christian Cyrus Leben is an American former mixed martial artist, referee, and bare knuckle boxer. A professional MMA competitor from 2002 until 2013, he most notably competed in the UFC in the Middleweight division, compiling a record of 12-10 in 22 appearances for the organization.
Leben first appeared in the inaugural season of The Ultimate Fighter reality series, and also fought in the now-defunct WEC. He began his UFC career with five victories in a row before suffering a knockout loss to future UFC Middleweight Champion Anderson Silva, and was known for his toughness and powerful left hand.
Leben was the inaugural WEC Middleweight Champion.
Leben is from Portland, Oregon and has one older brother and one younger sister. Growing up Leben enjoyed skateboarding, dirt biking, and snowboarding. When he was in middle school, he began watching the UFC and became very interested in MMA. He began training in boxing, and then was on the wrestling team at Benson Polytechnic High School, picking up the sport rather quickly.
Today Chris trains individual clients virtually and in-person. He is planning on opening a gym in the near future and is looking forward to more refereeing opportunities.
