Ray Borg and Demetrious Johnson will reportedly not be fighting in Saturday's main event at UFC 215 in Edmonton, Canada.
On Thursday, Ariel Helwani of MMA Fighting reported Borg had to withdraw from the scheduled bout because of an illness. The women's bantamweight title fight between Amanda Nunes and Valentina Shevchenko will be the replacement pay-per-view main event.
Helwani cited sources who said Borg "was deemed unfit to fight by UFC doctors," although he noted the illness was not related to the fighter's weight cut.
According to Helwani, there are no finalized plans for rescheduling, but he granted the organization would prefer to rebook the flyweight title fight as soon as possible.
