18-year-old Adrian Lee, younger brother of Angela and Christian Lee, set for debut at ONE 167 in June

Adrian Lee, the 18-year-old prospect hailing from the same family as ONE Championship lightweight and welterweight champion Christian Lee and former ONE atomweight champion Angela Lee, is set to make his professional debut at the upcoming ONE 167 card, which takes place on June 8 from the Impact Arena in Bangkok, Thailand.

Lee clashes with Antonio Mammarella in a lightweight bout, which airs on Prime Video in the United States.

Lee is the youngest member of his family, with three older siblings who all competed in ONE Championship prior to his arrival.

He signed with ONE Championship this past December and now he’s set to make his debut in June.

Growing up in Hawaii, Adrian learned martial arts under his father while training alongside his siblings in what has become a family business in MMA.

His sister Angela became one of the faces of ONE Championship during her fast rise to fame before announcing her retirement from the sport this past September to focus on her mental health. Christian Lee currently holds titles at both welterweight and lightweight after he debuted for ONE as a teenager as well.

Adrian’s older sister Victoria also competed in ONE Championship before her tragic death in 2022.

The latest Lee sibling looks to carry on the family tradition against Mammarella, who sports a 1-0 record in his pro career with eight additional bouts as an amateur.

ONE 167 features an atomweight title fight at the top of the card as reigning champion Stamp Fairtex defends her belt against Denice Zamboanga in the main event.
