Ultimate Fighting Championship (UFC) will finally deliver the most expensive show it ever produced, UFC 306 at The Sphere for Noche UFC during Riyadh Season. The pay-per-view (PPV) action, headlined by the bantamweight title fight pitting reigning 135-pound titleholder Sean O'Malley against No. 1-ranked contender Merab Dvalishvili, takes place this Sat. night (Sept. 14, 2024) in Las Vegas, Nevada, and will run head-to-head with the Canelo Alvarez boxing fight across town in "Sin City."

UFC 306 will also feature the women's flyweight title fight between current 125-pound champion Alex Grasso and former division titleholder Valentina Shevchenko, who recently wrapped filming on The Ultimate Fighter (TUF) 32. Elsewhere on the card (see it here), former featherweight title challenger Brian Ortega makes his last stand at 145 pounds opposite Brazilian jiu jitsu wizard Diego Lopes. In addition, bantamweight phenom Raul Rosas Jr. makes his 135-return against Aoriqileng.
