"UFC 290: Newcomer Josiah Harrell's Fight Cancelled Due to Brain Disease"
UFC newcomer Josiah Harrell has been forced to withdraw from his debut fight at UFC 290 after a pre-fight MRI revealed he has moyamoya, a rare brain disease. Harrell will need to undergo brain surgery, and his manager sees the discovery as a "blessing in disguise" as it would have been dangerous for him to continue fighting. This situation is similar to what happened to Vince Murdock in 2019, who made a full recovery and returned to fighting after an MRI revealed moyamoya. Harrell's opponent, Jack Della Maddalena, was originally scheduled to fight Sean Brady, who withdrew due to injury.
