Aside from the stakes involved, the excitement is warranted since 'The Menace' was supposed to challenge Stamp for the gold last June at ONE 167. However, the Fairtex Training Center product tore the meniscus in her left knee during training camp, which forced her off the card.
Denice Zamboanga hopes to bring honor to the Philippines at ONE 173
After becoming the first-ever Filipina MMA world champion by capturing the ONE interim women's atomweight MMA world championship with a TKO of Alyona Rassohyna this past January, Denice Zamboanga hopes to give the Philippines even more reason to be proud of her come ONE 173.
The T-Rex MMA Training Center affiliate recently told ONE:
"Representing my country on such a grand stage fills me with immense pride. I am ready to give my all and bring honor to our nation."
