Today, ahead of that bout, the fighters took part in their weigh in with both coming in sport on the divisional limit.
For Nakazawa the weight has been his norm, give or take ½lb, for almost 5 years and is the 15th time he has been between 139½lbs and 140lbs.
For Okada, who is fighting for the first time since suffering a thumb injury in sparring last year, this sees him weighing in at 140lbs, on the button, for the 11th successive fight, going all the way back to his debut back in 2011.
Okada returns with intent to reclaim unified throne!
