Christian Lee puts ONE lightweight title on the line against unbeaten grappling star Tye Ruotolo

ONE lightweight champion Christian Lee will put his title on the line against unbeaten grappling sensation Tye Ruotolo at ONE The Inner Circle 37 on November 6 at Lumpinee Stadium in Bangkok, Thailand. ONE officials confirmed the matchup on Monday, with the full card yet to be announced.

Lee is one of the most decorated fighters on the ONE roster, having claimed titles across multiple divisions throughout his career. His most recent outing came last November, when he stopped Alibeg Rasulov by TKO to retain the lightweight belt — a performance that underlined his status as one of the promotion’s premier champions.

Ruotolo arrives as one of the more intriguing challengers in recent ONE history. The 23-year-old and his brother Kade built a formidable reputation in competitive grappling before transitioning to MMA, and Tye has carried that momentum into the cage, going 2-0 in ONE Championship with both victories coming inside the promotion. His November 6 title shot represents a significant leap in competition, however, as he steps up to face a seasoned champion for the first time.

The contrast in experience makes for a compelling matchup. Lee brings championship pedigree and proven finishing ability across multiple weight classes, while Ruotolo offers the kind of elite submission threat that has troubled even experienced MMA fighters. Whether Ruotolo’s grappling credentials translate against a champion of Lee’s calibre remains the central question heading into ONE The Inner Circle 37.
