The UFC 321 main card has five fights on offer. The event is set to take place on Saturday, Oct. 25, at the Etihad Arena in the United Arab Emirates (UAE).The pay-per-view will be headlined by a heavyweight title clash between reigning champion Tom Aspinall and former two-time challenger Ciryl Gane. The event marks Aspinall's first fight since being officially crowned undisputed champion following Jon Jones' short-lived retirement.Aspinall enjoys a near-flawless run in the UFC. Apart from a TKO loss to Curtis Blaydes due to a knee injury, the Briton is undefeated in the promotion. He is currently on a three-fight win streak, getting his lick back on Blaydes via Round 1 KO in his most recent fight at UFC 304.Gane is 2-0 since conceding a first-round submission loss to Jon Jones in their UFC 285 title fight. However, a loss this weekend could effectively remove him from the title picture for the foreseeable future.In the co-main event, Mackenzie Dern and Virna Jandiroba will lock horns for the strawweight title Zhang Weili vacated before moving up to flyweight for a super fight against Valentina Shevchenko.Check out Tom Aspinall and Ciryl Gane face off ahead of their UFC 321 fight below: View this post on Instagram Instagram PostUFC 321 main event walkoutsThe main event of UFC 321 is set to kick off at 2 PM ET (Eastern Time) / 11 AM PT (Pacific Time), and for fans in the UK, 7 PM BST (British Summer Time).
