Adrian Lee To Make Professional MMA Debut Against Antonio Mammarella At ONE 167

Adrian Lee has officially put pen to paper for his ONE Championship debut.

The youngest member of the famous fighting family will face Italian newcomer Antonio Mammarella at ONE 167: Stamp vs. Zamboanga on Prime Video, which airs live in U.S. primetime on Friday, June 7.

After being touted as one of MMA’s best amateur prospects, the 18-year-old Singaporean-American is turning his attention to the professional ranks for this lightweight clash at the Impact Arena in Bangkok, Thailand.

Lee’s older siblings have all competed in ONE Championship – former longtime ONE Women’s Atomweight MMA World Champion “Unstoppable” Angela Lee, reigning ONE Lightweight and Welterweight MMA World Champion Christian “The Warrior” Lee, and the late Victoria Lee.

Primarily training alongside Christian in Hawaii, the young phenom knows exactly what level he must reach to achieve his lofty goals.

Adrian has already built a solid body of work as a decorated amateur champion in MMA, kickboxing, and pankration, as well as a state wrestling champion in Hawaii, but his move up to the world’s largest martial arts organization will be his toughest test yet.

Mammarella fights out of Sydney, Australia, and is stepping onto the global stage with a professional MMA victory under his belt.

The 24-year-old earned a TKO in his debut last December following a successful career in the amateur ranks.

He now joins his unbeaten teammates, Coopar Royal and Faine Mesquita, on the ONE roster, with their MMAFFT team building a solid reputation after some impressive recent performances.

Given the Lee family’s elite pedigree, fans will be eager to see how Adrian fares when he steps into the Circle for the first time, but Mammarella knows he can make a statement in this high-profile ONE debut.

With a World Championship doubleheader of Stamp Fairtex vs. Denice Zamboanga and Tawanchai PK Saenchai vs. Jo Nattawut confirmed atop the lineup and a supporting bill littered with exciting contests, the card for ONE 167 is looking stacked from top to bottom.

Stay tuned to for all the updates ahead of ONE 167 on June 7.
