Khabib Nurmagomedov holds a black belt in Judo and has also competed in Sambo. He is a 2 time Russian Combat Sambo Champion and a 2 time World Sambo Champion. He began his MMA career in 2008 and hasn't looked back racking up wins for Pankration, M-1 and ProFC bringing his record to 16-0. The UFC would take notice and sign the rising star and he would not disappoint finishing 2 out of 4 opponents in the Octagon. He would pick up the wins over some tough veterans in, and a win over in his debut. He followed it with a dominating victory over striker at UFC 160, by putting on a grappling clinic and scoring a record number of take downs in a UFC fight (21 out of 27 attempted). Khabib's next UFC fights were at on September 21st, 2013 against and on April 19th, 2014 against at Khabib earned unanimous decision victories in both fights running his undefeated MMA record to 22-0.

Khabib tore his meniscus training for a fight against Cowboy and tore it once more when the fight was rescheduled. He was scheduled to face Tony Ferguson at the TUF 22 Finale, but broke a rib in training.

After two years of being plagued with injuries, Khabib finally returned to the octagon on April 16th 2016 to face Pennsylvania prospect Darrell Horcher, who replaced the injured Tony Ferguson. After a brief feeling-out process in round 1, Khabib quickly finished Horcher via ground-and-pound TKO in round 2. The UFC sought to bring Khabib and Tony Ferguson once more into the octagon for UFC on FOX 19, however the fight was canceled yet again.

This time, however, it was Ferguson who pulled out due to injury. Michael Johnson replaced the injured Ferguson and the bout was rescheduled for UFC 205. The first round saw Khabib encountering a fleeting moment of adversity, when Johnson hit Khabib with a quick right hook, causing the Dagestani to wobble briefly. However, that was only highlight of Johnson's night, as Khabib delivered a one-sided beating which ended in a submission victory via Kimura. Coming off a dominant victory over Michael Johnson, Khabib was scheduled to face Tony Ferguson for the third time at UFC 209. All signs were pointing to both fighters making it to the cage in the lead up.

However during weigh-ins, Khabib was nowhere to be found. It was later reported that he entered a hospital due to complications stemming from a bad weight cut. The fight was canceled. Nine months later, Khabib faced Edson Barboza at UFC 219.
