The champion, the unbeaten Amnat Ruenroeng (13-0, 5) weighed in at a little less than 110lbs whilst mandatory challenger McWilliams Arroyo (15-1, 13) weighed in around 111lbs.
For Amnat this is his lowest recorded weight and he is more than 2lbs under the weight that he was last time out. In fact he is nearing the Light Flyweight limited. As for Arroyo he is at the lowest he's been in more than 2 years, though he has been marginally lighter once in the past.
The men, who both looked in terrific shape, will be in the ring tomorrow between 15:00 and 17:00 local (Thai) time with their bout to air on Thai channel 7. It will be the third Flyweight title bout in less than a week and the winner will likely be the focus for both Naoya Inoue and Zou Shiming who are both on the hunt for a Flyweight title fight later this year.
This bout really is a boxer against a puncher contest and one that we're excited about. We're not as excited as we were for Friday's bout between Roman Gonzalez and Akira Yaegashi but it is still a fight we're really excited about.
