Khabib Nurmagomedov's father Abdulmanap is in hospital with "pneumonia and flu symptoms" according to reports in Russia.
renowned commentator Ramazan Rabadanov told local media : "Abdulmanap is in Makhachkala, in the Second City Hospital. He got sick in the mountains.
"He walked for two days, the brothers barely persuaded to go to the hospital. While coronavirus is not confirmed, they say the flu. No one is allowed to visit him."
Khabib himself is supposedly not even allowed to check on his father while he is sick.
Abdulmanap, who is 57 years old, trains his son as well as several other famous Russian UFC fighters.
Rabadanov also shared a picture of himself with Khabib's father, saying: '"(He) almost managed to build a park, took out the trash, planted an alley from new trees, put beautiful benches along the roads, and yesterday didn't come to the park.
"Hopefully the pneumonia doesn't catch my friend and he comes to the park again."
Khabib posted a photo of his father on his Instagram just last week with the caption: "Time is not easy for all of us, pay attention not only to your family, but also to your parents, because parents are the keys to Paradise.
"Appreciate the parents, because those who no longer feel sorry for them and would give everything that they have, just to sit with them for 5 minutes over a cup of tea."
Before the coronavirus pandemic hit Khabib was due to take on Tony Ferguson at UFC 249.
But the Russian was unable to take part in the fight after he was denied entry to the United States.
UFC President Dana White did his utmost to ensure the event could go ahead with a private island prepared to be the host venue.
But White has since had to back down after executives from ESPN and Disney told him to forget his controversial plans.
