UFC 253, the latest pay-per-view instalment in the world's lead mixed martial arts promotion. The event is the <a href="https://www.thenational.ae/sport/other-sport/return-to-ufc-fight-island-confirmed-as-khabib-nurmagomedov-and-israel-adesanya-top-insane-lineup-in-abu-dhabi-1.1079344">first of five on Fight Island 2</a>, the UFC's second residency in the capital. It follows on from this summer's hugely successful inaugural run. While July featured four events, opened by UFC 251, this will comprise five, and is bookended by two pay-per-view shows: UFC 253 and UFC 254. The Fight Island concept was created in response to the coronavirus crisis, allowing the UFC’s international athletes to compete during the pandemic. The promotion has a strong relationship with Abu Dhabi, <a href="https://www.thenational.ae/sport/other-sport/ufc-president-dana-white-excited-by-mind-boggling-five-year-plan-for-mixed-martial-arts-in-the-uae-1.907460">underlined by a five-year agreement</a> signed last year between the two parties. September 27. The early prelims kick off at 3am UAE time, the prelims at 4am, and main card at 6am. Once more, Fight Island will be housed in a designated “safe zone” on Yas Island. The zone is open only to fighters, coaches, UFC staff and other personnel deemed necessary to the operation. For the inaugural series, all events took place at Flash Forum. In accordance with public health guidelines, no fans will be allowed to attend the events.
