Borg (11-2) has won five of seven UFC fights, but also previously pulled out of a bout on short notice.
The UFC medical team was unable to clear Borg ahead of his fight against 125-pound champion Demetrious Johnson.
Dana White is facing yet another scheduling nightmare with disaster striking UFC 215 on the weekend.
A lingering illness for Ray Borg has scrapped the UFC 215 main event.
Then, Nunes said she followed her coach's suggestion and her own hunch that the sinus illness she suffered with on the morning of her UFC 213 main event in Las Vegas was too severe to fight with, leaving the UFC to offer refunds. Saturday's UFC 2015 card, featuring a women's bantamweight title fight between champion Amanda Nunes and challenger Valentina Shevchenko, will go on as scheduled. "Best shape I've ever been in my life". "He's my boss. I'm not going to fight with the person who's feeding me". Instead, the fight's cancellation is just another in what has been a bad-luck calendar year for UFC coming off of a record-breaking 2016 campaign, which saw the company change owners following a much-publicized $4 billion sale. Their fight will proceed as one of 11 bouts on the card.
A flyweight bout between Henry Cejudo and Wilson Reis will be moved from the prelims to pay-per-view to fill the empty spot on the main card. He is the first, current, and only UFC flyweight champion.
The fighters will hit the scales at 6 p.m. ET on Friday.
