Saturday's heavyweight fight between Derrick Lewis and Jhonata Diniz at UFC Edmonton at Rogers Place has been canceled.
UFC officials said the last-minute cancellation was due to Lewis suffering from a "non-weight cut related medical issue" that rendered him unable to compete.
Lewis (28-12) weighed in Friday morning right at the 266-pound limit for a nontitle heavyweight fight. However, he did not show up for the ceremonial weigh-in later in the day. A reason was not given, and it was suggested that Lewis would still be able to compete.
UFC officials later said Lewis was out of the event and that his fight with Diniz (8-0) was canceled.
With the main card losing a fight, a women's flyweight bout between Jasmine Jasudavicius and Ariane da Silva will fill the vacancy.
UFC Edmonton will be headlined by a flyweight battle between former champion Brandon Moreno and Amir Albazi.
