Reigning ONE Featherweight World Champion Martin Nguyen  is back in action against Koyomi Matsushima.
The 30-year-old Nguyen has become one of the most prolific Asian martial arts talents over the past few years, winning 8 of his last 10 contests. In 2015, he embarked on an unprecedented six-bout winning streak. Along the way, he captured both the ONE Featherweight and ONE Lightweight World Titles to become a simultaneous two-division ONE World Champion.
After falling to injury, however, Nguyen was prompted to vacate the lightweight belt in September 2018. After Nguyen fully recovered from injury, the Vietnamese-Australian sensation returned to action against dangerous veteran Narantungalag Jadambaa, delivering a flying knee knockout victory.
The 26-year-old Matsushima is one of the fastest rising martial artists from Japan. Hailing from Kanagawa prefecture located in the Kantō region of Japan, Matsushima has put together a handful of solid performances while competing in local Japanese martial arts promotions Pancrase and Shooto.
In his ONE Championship  debut last September, Matsushima scored a stunning first-round technical knockout victory over former ONE World Champion Marat Gafurov, announcing his arrival on the global stage of martial arts competition. In his most recent outing last June, Matsushima dominated top Korean featherweight Kwon Won Il to win by unanimous decision.
Now, Matsushima has earned his opportunity to challenge Nguyen for the ONE Featherweight World Championship.
