In what seems to be becoming a regular occurrence at some UFC events…the main event between Demetrious Johnson and Ray Borg has been called off due to an illness to Ray Borg which is stated,by his nutritionist, to not being related to the weight cut. This clarification seems to have been given because Ray Borg has had issues with weight cuts in the past. The UFC doctors have declared him unfit to fight as he was struggling with an illness all week long.
As a result, the Amanda Nunes vs Valentina Shevchenko fight has been bumped up as the main event.
