Khabib Nurmagomedov’s father, Abdulmanap Nurmagomedov, died on Friday at the age of 57.

According to RT.com (via CNN’s Ben Morse), Abdulmanap died in a Moscow hospital from COVID-19-related problems. In May, Khabib’s manager, Ali Abdelaziz, informed ESPN’s Brett Okamoto that Abdulmanap was in a medically induced coma following a coronavirus diagnosis.

Abdulmanap had already had heart surgery and was evacuated from Dagestan to Moscow in May. Abdulmanap, Khabib’s father, was also the unbeaten fighter’s trainer for many years. Abdulmanap was skilled in a variety of sports, including wrestling, judo, and sambo.

Abdulmanap was also the combat sambo national team coach in his home Dagestan.

Khabib has a 28-0 professional MMA record under Abdulmanap’s tutelage, with 10 wins via submission and eight by knockout. He overcame McGregor by submission at UFC 229 in 2018 and most recently defeated Dustin Poirier by submission at UFC 242 last year.

Khabib was supposed to fight Tony Ferguson at UFC 249, but travel limitations imposed by COVID-19 prohibited him from doing so.
