Petr Yan may have been the only person at UFC 323 on Saturday night who believed he’d dethrone Merab Dvalishvili for the bantamweight title. But even he couldn’t have foreseen the dominance he’d put forth in doing so.In one of the greatest against-the-odds performances in recent memory, Yan toppled MMA’s frontrunner for Fighter of the Year and recaptured the UFC bantamweight championship with a lopsided upset of Dvalishvili to cap off the final UFC pay-per-view of the year — and potentially ever.Yan defended 27 of Dvalishvili’s 29 takedowns attempts, landed five of his own, and soundly out-struck the feared Georgian to secure a revenge win few saw coming. Making the performance even more impressive, Dvalishvili entered the night riding not only the longest win streak in UFC bantamweight division history (13), but also the fourth-longest win streak in overall company history (14).Yan’s beatdown was so thorough and shocking that even the new champ’s fellow fighters couldn’t quite believe what they were watching.Check out how the MMA world reacted to Yan vs. Dvalishvili 2 below.Merab, you are one of the greatest to ever step into this cage.
