UFC officials have confirmed the cancellation of the highly anticipated UFC 290 bout between Josiah Harrell and Jack Della Maddalena due to a medical issue involving Harrell. Della Maddalena is on a 14-fight win streak in the UFC. His last victory in the Octagon came against Randy Brown at UFC 284 in February.
Initially, the UFC scheduled Della Maddalena to fight Sean Brady at UFC 290. Brady withdrew from the event due to an issue with his left elbow, leading to Harrell’s inclusion as a replacement fighter. However, it has now been revealed that Harrell’s pre-fight brain MRI potentially saved his life.

The issue came to light during Harrell’s pre-fight MRI. This is a mandatory requirement for clearance by the Nevada State Athletic Commission (NSAC) to compete in the UFC. Blanco also said the diagnosis came as a “blessing in disguise” due to the risks of competing with such an affliction being very high. Harrell is scheduled to undergo a brain procedure in the near future.
Harrell’s removal from the fan rankings is disappointing. However, his manager has clarified that they have not received any release from the UFC. This could indicate a potential future return to competition.
UFC pre-fight medical examinations may have saved more lives
It is important to note that Harrell’s case does not represent the first occurrence of a UFC fighter receiving a diagnosis of Moyamoya syndrome, a rare condition. In 2019, Vince Murdock underwent surgery for the same condition before a UFC bout. Subsequently, both doctors and the UFC cleared him to compete. And has since made successful appearances on Dana White’s Contender Series and The Ultimate Fighter.
