If proof were needed that Conor McGregor remains the biggest draw in UFC, then it arrived late on Monday – from the man himself. The Irishman, a former two-division champion, posted on social media evidence of the total pay-per-view buys for his rematch against Dustin Poirier at <a href="https://www.thenationalnews.com/sport/other-sport/ufc-257-conor-mcgregor-gutted-after-defeat-to-dustin-poirier-in-abu-dhabi-1.1152363" target="_blank">UFC 257 in Abu Dhabi in January</a>, with the document reporting the event racked up more than 1.5 million buys. With that figure in mind — 1,504,737 to be exact — McGregor has been part of every one of the top five highest-selling pay-per-views in UFC history (and eight of the top 10). For instance, his trilogy fight with Poirier, <a href="https://www.thenationalnews.com/sport/ufc/2021/07/12/ufc-264-conor-mcgregor-vows-to-return-better-than-ever-following-gruesome-leg-break/" target="_blank">at UFC 264 in July</a>, is estimated to have sold around 1.8m. The former featherweight and lightweight champion, who earlier this year was named by Forbes as the highest-earning athlete in sport, is currently recovering from a broken leg sustained in that summer defeat to Poirier in Las Vegas. 1) 2.4m: McGregor v Khabib Nurmagomedov, UFC 229, T-Mobile Arena, October 2018.
