We know Adesanya vs. Imavov is the main event, and its expected that No. 14 Shara Magomedov vs. Michael Venom Page will serve as the co-main event.It would make sense for heavyweight contenders No. 4 Sergei Pavlovich and No. 9 Jairzinho Rozenstruik to feature on the main card, as well as Silva-Jasudavicius. From there, the UFC and ESPN will have plenty of options for structuring the card.MORE FOR YOUFor the first time in his career, Israel Adesanya is on a two-fight losing streak. Hes coming off a loss to Dricus du Plessis in August at UFC 308. Before that, Adesanya lost the middleweight title to Sean Strickland in September 2023. A third straight loss would be devastating for the 35-year-old future Hall-of-Famers status as a contender.Imavov, 28, is moving in the opposite direction. Hes on a three-fight win streak and hasnt lost a fight since dropping a unanimous decision to Strickland in January 2023. Imavov was a perfect 3-0 in 2024 with wins over Roman Dolidze, Jared Cannonier, and Brendan Allen. A win over Adesanya could position Imavov for a title shot or at least a No. 1 contenders fight.The co-main event is almost as intriguing. Few stars are rising as quickly as Magomedov. In a year that didnt include Max Holloways unbelievable KO win over Justin Gaethje, Magomedovs double spinning-backfist KO of Armen Petrosyan at UFC 308 would have been the knockout of the year.Magomedov has positioned himself as one of the best pure strikers in the UFC, and that skill will be tested against Page. While the veteran is moving up from welterweight, theres a chance we could see the best version of Page against Magomedov. He wont have to worry about Magomedov taking him down. Instead, we should see an entertaining stand-up battle.Be on the lookout for more definitive information about the full Saudi card, including the bout order.
