Today the two men took part in their weigh in for the contest, and both men came in comfortably under the 108lb limit, in fact both came in around 107.4lbs and both looked very comfortable and relaxed.
Ken Shiro, who won the title earlier this year with a close deicison win over Ganigan Lopez, is actually at a career lowest weight and it shows just how seriously he is taking this bout. It should be noted that as hard as his preparation has been he was still having fun at the weigh in and he struggled massively to keep a serious face during the face off, bursting out in to a smile when he was staring at Guevara.
Guevara has been lighter than he was today, though he hasn't been in a while. Notably he was lighter in his career defining victory over Akira Yaegashi, in December 2014, when he came in under 107lbs, and he was also lighter in his successful defense against Filipino Richard Claveras.
Whilst the bout isn't expected to be televised live there is a lot of talk that the bout will be featured at a later date on a Fuji TV sister station, much like Ken Shiro's title win over Lopez was.
