The Build-Up
Sean O'Malley had been 17-1 (1 NC) coming into UFC 292 with a three-fight UFC win streak including a controversial split-decision win over Petr Yan at UFC 280. He was the most-marketed bantamweight of the modern era — long hair, vivid gear, and a striking style built on power and range — but had not yet beaten a top-three bantamweight.
Aljamain Sterling was the dominant bantamweight champion with three title defenses. He was a -210 favourite; O'Malley's win probability was widely estimated at 30-35%. The Suga Show's striking was feared but his grappling defense against Sterling's elite wrestling had been identified as the critical question. Most analysts picked Sterling via takedown control in the later rounds.
Main Event: Sterling vs. O'Malley
Round one was Sterling's. The champion used his wrestling to score a takedown at 1:30, controlled top position for two minutes, and landed sustained ground-and-pound. O'Malley scrambled to his feet at 3:30 and landed a clean jab, but the round went clearly to Sterling. The judges had it 10-9 Sterling.
Round two produced the upset. O'Malley used his range to control the standing exchanges from the opening of round two, landing clean jabs and counter rights. At 2:30, he landed a clean overhand right that wobbled Sterling against the cage. He pressed with sustained combinations; a right hand at 2:50 dropped Sterling to the canvas. Four follow-up strikes against the downed champion brought referee Marc Goddard in at 2:58.
Sean O'Malley was the UFC bantamweight champion. In his post-fight interview he said: "They said I couldn't do it. They said Aljamain Sterling was too good. Sugar show, baby." The TD Garden crowd gave him a sustained ovation.
O'Malley defended the title against Marlon Vera at UFC 299 in March 2024 (UD) and against Merab Dvalishvili at UFC 306 in September 2024 (UD loss — Dvalishvili won the title). His championship reign lasted approximately 13 months.
Co-Main Event: Zhang vs. Lemos
Zhang Weili defended the strawweight title in 6:32 across two rounds. Round one was competitive — Amanda Lemos pressed forward with her power striking and wobbled Zhang at 3:00 with a clean left hook. Zhang recovered and scored a takedown in the final minute. Round two ended at 1:32 — Zhang transitioned from a body lock into a tight armbar, Lemos defended briefly before tapping. Zhang Weili's first successful strawweight title defense of her second reign was complete.

Legacy & Impact
UFC 292 is remembered as the night Sean O'Malley's star power was validated with a championship. The Suga Show had been the UFC's most-marketed bantamweight for two years; the KO of Sterling confirmed that his striking power translated to the championship level. His 13-month championship reign (August 2023 to September 2024) produced a title defense against Marlon Vera at UFC 299 before the loss to Merab Dvalishvili at UFC 306.
For Aljamain Sterling, the KO loss was the formal close of his bantamweight championship reign. He went on to fight Movsar Evloev at featherweight at UFC 298 in February 2024 (UD loss) and has not fought since. His bantamweight legacy — three successful title defenses, the first DQ title win in division history, and one of the most decorated bantamweight technical games of the modern era — stands independent of the O'Malley loss.
