On the scales both men made the weight, relatively comfortably, with each man hitting the scales at slightly over 117¾lbs, well inside the 118lb limit.
For Kameda this is slightly heavier than he was last time out, when he defeated Alejandro Hernandez, in a split decision that was closer on the cards than anyone thought it should have been, and slightly lighter than he was in his US debut, when he blew away Pungluang Sor Singyu with a devastating body shot.
As for McDonnell it's heavier than he's been in his last couple of bouts. Last time out he was 117lbs dead on, for what was a less than inspiring win over Javier Nicholas Chacon, whilst he was 117½lbs for his title winning bout against Thailand's Tabtimdaeng Na Rachawat.
Although both men weighed the same it did seem like McDonnell was the tall man at the weigh in, and by more than the 1" listed on various sites.
