Josiah Harrell was set to make his UFC debut on Saturday, but that took a back seat to his health on Friday.
Nolan King of USA Today's MMA Junkie reported Harrell's manager, Maurice Blanco, said the fighter's pre-fight brain MRI revealed moyamoya syndrome. Moyamoya syndrome is a rare disease that increases one's risk for a stroke because of blocked arteries at the base of the brain.

Harrell, who will no longer fight Jack Della Maddalena, will undergo brain surgery.
