According to UFC President Dana White, UFC middleweight champion Robert Whittaker is out of his bout with Kelvin Gastelum at UFC 234. The previous co-main event, Israel Adesanya vs. Anderson Silva, is now the main event. Whittaker reportedly suffered a hernia and there is no timetable for his return as of this time. The fights at the Rod Laver Arena in Melbourne, Australia will move forward on pay-per-view, but this is a major setback for Whittaker, the organization and perhaps the middleweight division. One has to at least anticipate the inclusion of a middleweight interim belt being created.
