Diego Sanchez's struggle with COVID-19 has left him hospitalized.

Sanchez, a UFC Hall of Famer, posted an update last week, saying that he was doing better after qualifying for Regeneron monoclonal antibodies.

But since then, it appears that things have taken a turn for the worse, leaving him with low oxygen levels, blood clots in both legs and pneumonia that has attacked his respiratory system.

"Low oxygen numbers and a pneumonia. This has been some tying times," he posted on social media.

Despite experiencing severe symptoms from COVID-19, Sanchez said he hasn't taken his vaccination shots yet.

"I'm going thru it but I can't say I'm sold on the vax at the current moment in time," he tweeted.

Sanchez, who parted ways with the UFC in April, is currently a free agent. In August, Bare Knuckle FC president David Feldman told MMA Junkie that a deal to sign Sanchez was almost finalized but not until he was medically cleared to compete.

Sanchez's departure from the UFC came after a dispute between his then-manager, Joshua Fabia, and the promotion's brass over Sanchez's medicals. Sanchez later separated from Fabia as his manager and business partner.
