Yesterday, as part of the formalities for the bout, both men took part in their weigh in and both made the 126lb limit with no issues.
On the scales Magsayo was a full 1lb under the limit, coming in at 125lbs for the bout. That's the the same weight as he's been for his last 2 contests and although we suspect he'd struggle to go down in weight he's certainly not a big Featherweight, though at just 21 the prodigious youngster he is still a young man filling out his body and it's clear that we could be some time from him really filling into his frame.
Interestingly Robles was the heavier man on the scales coming in at a career highest recorded weight of 125½lbs. Although the under-dog he won't fear Magsayo and has shared the ring with other highly regarded prospects, such as Joseph Diaz, Diego De La Hoya and Oscar Negrete. Sadly though the Mexican is 1-4 in his last 5 bouts. Whilst naturally the smaller man it is interesting to note that Robles has seemingly grown into a Featherweight after out growing the Super Bantamweight division earlier this year.
