Khabib Nurmagomedov doesn't even have a fight scheduled but he's keeping fit by swimming against the tide in a cold river in Dagestan, Russia.

Nurmagomedov, the UFC's reigning lightweight champion, defended his title at the UFC 242 show in Abu Dhabi in September, defeating Dustin Poirier in the third round with a rear-naked choke.

He has no opponent lined up to fight next, but is expected to return to the Octagon in March or April next year, potentially against number one contender Tony Ferguson.

Even though Nurmagomedov has no fight to prepare for, he is still busy training and a video has been posted on Instagram that shows him staying sharp in the Kizilyurt region of Dagestan, likely in the Sulak river that drains the mountainous water into the Caspian sea.

The video was posted by Nurmagomedov's friend known as King Farruh on Instagram, who shares a lot of photos of the fighter.

"Today was very cold, he doesn't care," a caption on the video read. "Water was very cold. I tried to put my feet and almost freeze my ass off."

In a nod to Nurmagomedov's probable opponent Ferguson, King Farruh added: "Tony, you're in trouble!"
