Only two months after Clash of Champions II, DEF Promotions held Fight Night 15 on 13th May, 2017. This 7-bout event featured boxers from 6 different countries: Japan, Thailand, Philippines, South Africa, Hong Kong, and the United Kingdom. For three years, Fight Night has been a popular event that was held at DEF Boxing Gym, and this event was a big step up to be placed at the Hong Kong Convention and Exhibition Centre, the biggest stage possible in the city. While Fight Night 15 stayed true to its form by filling most of the fight cards with local up-and-coming boxers, it also had top Japanese fighters as well. The main, and co-main event featured Japanese fighters, and because of that DEF Promotions invited plenty of Japanese media organisations over to cover the event.
The main event of the evening was headlined by Takuya Watanabe (31-7-1) and Terdchai Doungmontree (15-6-0). Watanabe was able to demonstrate his skills and powers with a three round technical knockout victory over his Thai opponent.
Additionally, this bout featured Ayumi Goto (6-0-0), who won via a fourth round technical knockout over Sumanthar Baenkham (1-2-0).
Furthermore, Fight Night 15 was a demonstration of DEF Promotions’ ability to fill the fight card with quality fighters, with Sho Kimura (13-1-2) defeating Wisitsak Saiwaew (2-4-0) in a second-round knockout. Only two months later, Sho Kimura shocked the entire world with an astounding performance by knocking out the most famous Chinese boxer Zou Shiming to win the WBO World Flyweight title before successfully defending it twice.
