It means the highly-anticipated No 1 contender match between Adesanya (15-0) and Brazilian legend Anderson Silva (34-8, 1nc) will now serve as the main event. "It wasn't a weight-cutting related issue or anything like that, it's just a very unfortunate hernia issue which may even require a procedure". He's fought hard to get to a title shot, and it's understandable he would be a little miffed at this last-minute pullout from Whittaker. The event was scheduled to take place in Melbourne, Australia, due to the 28-year-old's status as the first Australian to hold a UFC belt.
This marks the second time that Whittaker has been slated to fight in Australia, but been unable to compete because of complications. About a month before the event, Whittaker had to pull out with a staph infection in his stomach.
The cancellation of the bout poses the question of whether or not Gastelum will get the first shot at Whittaker's belt when he returns from injury, with the victor of the fight between Adesanya and Silva guaranteed a title shot.
There are a total of five fights on the main card.
