Overview
- The lightweight co‑main between Arman Tsarukyan and Mauricio Ruffy is set for UFC 331 on Sept. 19 at Crypto.com Arena in Los Angeles.
- Tsarukyan has publicly called the fight a must‑win and said a defeat could mean he never gets another shot at the UFC lightweight title.
- UFC president Dana White has not confirmed the bout as a guaranteed title eliminator, so a win may not automatically secure the next challenger spot.
- Non‑fight developments are a major part of the build: streamer N3on says he was paid to corner Tsarukyan and to supply a walkout song while Khamzat Chimaev has publicly praised Tsarukyan’s grappling and is reported as part of his corner plans.
- Tsarukyan’s urgency traces to a last‑minute back injury that removed him from a booked January 2025 title fight with Islam Makhachev and to uncertainty over champion Justin Gaethje’s availability, which together mean any clear, marketable win will be crucial to reopening his path to gold.
