Luis Gustavo wins RIZIN lightweight title with first-round knockout

Luis Gustavo claimed the RIZIN lightweight championship at RIZIN 53 on May 11, 2026, stopping Ilhom Nazimov inside the first round to become one of Asia's premier promotion's newest titleholders.

The card delivered finishes throughout, with American fighter Ryan Cafaro submitting Koyomi Matsushima via guillotine choke in the third round. Matsushima, the 33-year-old Japanese veteran from Gaio Gym, carries a 13-6 record and has built a reputation as an active striker, averaging 2.7 significant strikes per minute at 47 percent accuracy. He is also a notably active wrestler, averaging nine takedown attempts per 15 minutes, though Cafaro's submission work ultimately proved decisive in their contest.

Ryo Takagi added another first-round knockout to the night's highlight reel, finishing Kaiven Lee in what was one of several stoppages across the event. The main event between Ren Hiramoto and Koji Tanaka was contested under special stand-up rules with no weight class in play, and the two fighters went the distance in a bout that ended in a draw.
