The upcoming One FC 12 card has gotten some new addition as Melvin Yeoh faces AJ Lias Mansor in the Malaysian National Featherweight Tournament Finals, Gianni Subba faces Chen Yun Ting, Nik Harris faces Zuli Silawanto and Steven Durr faces Samir Mrabet. Yeoh earned his spot in the tournament finals after defeating Raymond Tiew by submission at One FC VII. Mansor is replacing the injured Jian Kai Chee and will enter the finals while riding a three fight losing streak. Subba is currently undefeated as a professional MMA fighter and has gotten all of his wins in the One FC promotion. Ting is also undefeated as a professional MMA fighter, with his lone appearance being a win over Ronald Low at One FC VIII.
Harris will be making his One FC debut in this fight and will do so on the strength of a two fight winning streak. Silawanto has only won one of two in One FC and he is a longtime veteran of the TPIFC Fights promotion. Durr is returning to action after being away for a year, but he is a veteran of the Xtreme Fighting Championships. Mrabet is currently undefeated as a professional MMA fighter, with both wins coming in the Malaysian Fighting Championships. One FC 12 takes place on November 15th from the Putra Indoor Stadium in Kuala Lumpur, Malaysia with Adam Kayoom and Nobutatsu Suzuki headlining.
