The under-rated Atsumi, arguably the best young Korean in the sport, will be facing off against well travelled Filipino Dennis Tubieron (19-7-2, 8), who has lost his last 4 but is more proven than anyone Atsumi has faced so far.
The Korean made his Japanese debut last year, beating Thailand's Songkhramchai Ektinakorn, though really came to prominence this year when he stopped the much touted Sho Nakazawa in 4 rounds. That win over Nakazawa is, by far, the best win that he has scored, however Nakazawa was more rated on his potential and his amateur pedigree rather than professional achievement.
When it comes to Tubieron he's well know by British fans for being a 12 round punch bag against Josh Warrington back in April 2015 and being stopped inside a round by Mitchell Smith. He has however frequented Japan losing to Hiroki Shiino, Takafumi Nakajima and Ryosuke Iwasa in the last 3 or so years. Despite those losses he is a step up for Atsumi who will know that a win here could potentially move him on to an OPBF title fight, whilst Tubieron will be in the ring looking to give his career a much needed shot in the arm,
