The bout will be for the vacant title, that was given up earlier this year by Tomoki Kameda ahead of his bout with Jamie McDonnell. For Pungluang, who actually lost in a title bout to Tomoki, this will see him attempting to recapture a belt that he briefly held in 2012-2013 whilst Akaho will be hoping to become a world champion for the first time, having previously come up short against Yota Sato.
At the moment it's looking like the bout will be held in Thailand, giving Pungluang a huge advantage, though that hasn't yet been made totally clear. If it's in Thailand then Akaho will be seeking to become the first Japanese fighter to win a full world title in Thailand*.
At the time of writing the men are the top two ranked contenders with the WBO. Akaho is the top ranked fighter whilst Pungluang is ranked #2. With the bout seemingly done we don't expect to see either man move in the rankings, at least not until the two men fight.
