On the scales both men came in at the divisional limit of 140lbs, though they did look very different with Konno towering over the champion by several inches. Konno also stated that he had had to lose significant weight for the bout, and it seems clear to say that he is the much bigger man naturally. Despite that being obvious he is also the less proven fighter and this will be his first fight at title level, and his first over the 10 round distance.
For Aso the bout is his first defense, but he's not focusing on defending his title, but instead on just winning, showing a burning hunger for victory, rather than caring too much about retaining his title, which would merely be a bonus.
