The weigh in for that bout took place yesterday, and both fighters came in on the divisional limit of 105lbs.
At the weigh in the height advantage of the challenger was clear, as he boasted several inches of advantage over the champion, but that maybe offset by the thickness of the champion, who always looks like an imposing fighters down at 105lbs.
Coming in to this bout Wanheng is seeking his 8th defense and would tie the 49-0 record of Rocky Marciano with a win here against the former WBO champion. However if Fukuhara can score what would be a notable upset, he would end a 23 fight recod Japanese fighters failing in world title fights in Thailand. That run, of 22 losses and a draw, is one of the most intriguing in boxing and shows the clear advantage Thailand has over Japan in one of the sports longest and most intriguing rivalries. A win would also see Fukuhara become a 2-time world champion.
