Taking its place at the top of the bill will be the former co-main event between Kiwi phenom Israel Adesanya and Brazilian legend Anderson Silva.
Robert Whittaker will have emergency surgery after pulling out of his middleweight title defence against Kelvin Gastelum at UFC 234.
That all changed just hours ago, this after UFC President told ESPN's Brett Okamoto that Robert Whittaker had suffered an injury and would no longer be able to defend his title against Kevlin Gastelum at tonight's highly anticipated UFC 234 event.
Evidently, Whittaker began complaining of pain in his abdomen during the middle of the night and was taken to the hospital.

That gave Scotland a 5m lineout, but Peter O'Mahony got up and slapped the ball back and Rory Best put it down. He said after the game: "It happens to him because he is who he is, that's going to happen".
The loss of Whittaker, who is on a nine-fight win streak, will certainly be a massive disappointment for many fans with UFC 234 tickets.
For all the good luck that the UFC had in keeping fights scheduled through January, February is not starting off the same way.
Silva was guaranteed a title shot by White if he defeats Adesanya at UFC 234 at Rod Laver Arena in Melbourne this weekend. Whittaker did compete in June 2018 against the man he defeated for the interim title, Yoel Romero, though that fight was not contested for Whittaker's championship due to Romero significantly missing weight.
