Nikolai Terteryan is quickly emerging as a rising force in the junior middleweight division, backed by elite amateur credentials, early knockout power and the support of Golden Boy Promotions!

Since turning professional in 2025, he has made an immediate impact, scoring a first-round knockout in his pro-debut at Save Mart Arena in Fresno and following it up with a third-round stoppage victory in his second bout in Orange County.

In June 2025, Nikolai and his twin brother Sebastian signed with Golden Boy, instantly becoming two of the sport’s most talked-about new prospects. A product of a true fighting family, he draws inspiration from his late father Tigran, a former heavyweight on the Armenian national team, as well as his older brother, an undefeated professional MMA fighter.

Before turning pro, Terteryan built a standout amateur resume, capturing gold at the 2023 European Games and representing Denmark at the 2024 Paris Olympics as a junior middleweight. After his amateur success, he relocated to Las Vegas to begin his professional career, training under respected coach Jamie Robinson, where his ring IQ and natural power continue to set him apart.
