Arman Tsarukyan Reaches No. 2 at Lightweight

Arman Tsarukyan has moved to No. 2 at lightweight in ESPN’s latest divisional rankings after producing a first-round knockout of Mauricio Ruffy at UFC 331. The result, delivered by an elbow to Ruffy’s face, gave Tsarukyan the type of emphatic finish ESPN said he needed to strengthen his standing as the likely first challenger for lightweight champion Justin Gaethje. The ranking change is notable not merely because Tsarukyan climbed a place, but because it came after a sequence of missed championship opportunities described in ESPN’s report.

Tsarukyan had previously been close to a lightweight title shot. In January 2025, he withdrew from a title fight because of injury one day before he was scheduled to compete for the belt. Later that year, the UFC passed him over twice while booking title bouts. UFC 331 therefore supplied a fresh competitive moment for Tsarukyan rather than a simple continuation of an uninterrupted march toward a championship challenge. His knockout of Ruffy put a decisive result alongside a changing ranking picture. ESPN’s latest update placed Tsarukyan above former champion Ilia Topuria, while identifying him as the likely first challenger to Gaethje.

A knockout reshapes Tsarukyan’s position

The central development is the combination of Tsarukyan’s UFC 331 victory and his new place in ESPN’s lightweight order. Tsarukyan stopped Ruffy in the opening round after landing an elbow to the face. ESPN characterized the performance as one that made Tsarukyan all but undeniable as the next challenger for the lightweight championship. That wording stops short of confirming a fight booking, but it makes clear how strongly the outlet viewed the result in the context of the division. Tsarukyan’s move to No. 2 also came at the expense of Topuria, a former champion. ESPN reported that Tsarukyan was boosted above Topuria in the latest rankings. The placement gives the Ruffy finish a measurable consequence within the outlet’s list: Tsarukyan is now directly behind only the division’s top-ranked fighter in ESPN’s lightweight hierarchy. The report does not provide a confirmed date, opponent or official announcement for a future Tsarukyan title fight, so his possible challenge remains a likely outcome rather than a finalized next step.

The timing adds important context to the rise. ESPN’s account does not present Tsarukyan’s current position as automatic. His January 2025 withdrawal removed him from a title fight one day before it was due to take place, and the later decisions to pass him over for two title bookings meant another performance was needed to reassert his case. Against Ruffy, Tsarukyan supplied a first-round finish rather than a close or ambiguous result. There was also little wider reshuffling in the ESPN update. Tsarukyan’s climb above Topuria was the only rankings movement mentioned in the report. Saturday’s other main-event winner, men’s flyweight champion Joshua Van, was already the top-ranked 125-pound fighter, while former champion Alexandre Pantoja remained No. 2. That limited movement helps isolate the significance of Tsarukyan’s change: his was the specific adjustment made after the UFC 331 action covered by ESPN.

What the latest ESPN update confirms

ESPN listed its results as current and its rankings as of Sept. 22. Its eligibility rules state that a fighter must have competed during the past 12 months or have an upcoming fight booked. A fighter removed for inactivity can be reinstated only after competing. Those rules provide the framework for the published list, while Tsarukyan’s UFC 331 appearance supplies a recent competitive result behind his placement. For Tsarukyan, the confirmed facts are clear: he beat Ruffy by first-round knockout, rose to No. 2 at lightweight and moved above Topuria. The broader title picture is also clearly framed by the source, with Gaethje identified as champion and Tsarukyan described as the likely first challenger. What remains unconfirmed is any formal bout announcement. Keeping those points separate preserves the weight of Tsarukyan’s performance without treating a rankings development as a finalized title-fight decision.

• Arman Tsarukyan knocked out Mauricio Ruffy in the first round at UFC 331 with an elbow to the face.
• Arman Tsarukyan rose above former champion Ilia Topuria to No. 2 at lightweight in ESPN’s latest rankings.

Arman Tsarukyan’s UFC 331 finish changed both the immediate conversation around his title prospects and his listed position at lightweight. After an injury withdrawal from a title fight in January 2025 and two later occasions when he was passed over for title bookings, Tsarukyan’s first-round knockout of Ruffy delivered a timely result. ESPN’s move to No. 2, its only reported rankings change, reinforces why Tsarukyan is now viewed as the likely first challenger for Gaethje’s championship, even though no future bout has been confirmed.
