Adrian Lee is set to make his jump to the big leagues.
The youngest of the famed Lee siblings will make his ONE Championship debut at ONE 167 when he faces Antonio Mammarella on June 7 at Impact Arena in Bangkok.
MMA Fighting first reported on the development.
Christian Lee revealed in early December 2023 that his younger brother, Adrian, just signed a professional contract with ONE Championship.
Nearly four months later, Adrian revealed he signed his first professional fight contract with ONE Championship but kept any details of his debut under wraps.
Adrian Lee is the youngest of the Lee siblings and his three older siblings all carved a path in ONE Championship.
His oldest sister Angela was the inaugural ONE women's atomweight MMA world champion. She retired from the sport in September 2023 to focus on her mental health and lead the non-profit organization, Fightstory.
Christian reigns as the ONE lightweight and welterweight MMA world champion and is expected to return to action this year.
Victoria was 3-0 in her career before her tragic death in December 2022.
Adrian Lee joins a stacked ONE 167 card in Bangkok
Adrian Lee couldn't have had a better ONE Championship debut than ONE 167.
The card could become one of the biggest events the promotion put out this year, with two world title fights sitting atop the marquee.
ONE women's atomweight MMA world champion Stamp Fairtex will defend her gold against close friend and former training partner Denice Zamboanga, while Tawanchai PK Saenchai defends the ONE featherweight Muay Thai world title against Jo Nattawut.
British Muay Thai icon Liam Harrison will return from injury when he faces Japanese standout Katsuki Kitano in a bantamweight Muay Thai showdown.
ONE flyweight submission grappling world champion Mikey Musumeci will go up to bantamweight to face old tormentor Gabriel Sousa in a non-title bantamweight submission grappling match.
ONE 167 also features the MMA debut of ONE lightweight submission grappling world champion Kade Ruotolo as he faces Blake Cooper.
The entire card is available live and free to all Prime Video subscribers in the United States and Canada.
