Quigg has spent his career being known for living in the gym, being super dedicated/fit. Ironic this happens after leaving Joe Gallagher (knowing some of his fighters).

I'll be the naive one and say it wasn't done on purpose, however, i'm pretty certain they're (Roach and him) confident they can sparko Valdez in a fire fight, so this is obviously not going to be detrimental. This could be like Corrales-Castillo II, where the extra weight was evident.
