UFC 213 was a pay-per-view marred by multiple fight cancellations, including the literal main event on fight day, and the end result was an absolutely awful buyrate. MMA Fighting’s Dave Meltzer has the details:
UFC 213 on July 8, the show that lost its main event of Amanda Nunes vs. Valentina Shevchenko at the last minute, is currently projected to do in the range of 125,000 to 150,000 buys. With the headliner of Robert Whittaker vs. Yoel Romero for the interim middleweight title, that could wind up as the lowest UFC number for a pay-per-view event, with the exception of some shows headlined by Demetrious Johnson, over the last decade.
