Umar Nurmagomedov bounced back from the only loss of his career at UFC 321. Seizing the moment, the fighter made a daring callout to Merab Dvalishvili and Petr Yan, who are scheduled to lock horns for a bantamweight title clash at UFC 323 in December.In his main card fight against Mario Bautista, the Dagestani employed a grappling-heavy game to outpoint his opponent to a unanimous decision win.Right from the opening bell, Khabib Nurmagomedov's protege put immense pressure. While he got caught in a seemingly tight toe hold in the opening round and was monetarily dropped with a knee strike in the second, Nurmagomedov was largely able to control the fight with takedowns and positional control using body locks.Despite the convincing win, the 29-year-old showed true humility during his post-fight interview, admitting that he still considers himself an amateur in wrestling and has a long way to go before reaching the levels of his legendary cousin Khabib.The No.2-ranked bantamweight contender then directed his attention to Dvalishvili and Yan, saying:"Believe me, I will be ready, [a] 100 times better than today. I will do it, and I will come to take this belt. Doesn't matter who is going to be Petr Yan, Mirab [Dvalishvili] whoever else? Doesn't matter, guys, I will become champion."Check out Umar Nurmagomedov's callout to Merab Dvalishvili and Petr Yan below:The only loss of Nurmagomedov's MMA career came against Dvalishvili at UFC 311, where he dropped a unanimous decision to the Georgian following five closely contested rounds.Following his win in Abu Dhabi, he is now 19-1 in MMA, with wins against the likes of Cory Sandhagen and Bekzat Almakhan, among others.Elsewhere at UFC 321, Mackenzie Dern earned a unanimous decision win against Virna Jandiroba to claim the vacant women's strawweight title.
