Disaster has struck one day out from the first pay-per-view of 2025, with Arman Tsarukyan out of UFC 311.

Years on from their competitive collision at a 2019 UFC Fight Night in Moscow, which the Russian won on the scorecards, the pair were set to do battle for Makhachev's lightweight crown on Jan. 18.

But during the weigh-ins, a report from Red Corner MMA emerged revealing that Tsarukyan has withdrawn just north of 24 hours out from his first title challenge on mixed martial arts' biggest stage.

Dana White later confirmed the news himself on social media, while also announcing that Renato Moicano will step in to challenge Makhachev in tomorrow night's headliner.

While he is only ranked #10 in the division, he is riding a four-fight win streak. He's also coming off a dominant showing opposite Benoît Saint Denis in Paris, a similar result that netted Dustin Poirier a title shot against Makhachev last year.
