Question regarding Yoan Boyeaux-Benjamin Alcides Cantero

[KSTAT124]

Benjamin Alcides Cantero (Global ID #548138) in his first 17 bouts never weighed in at less than 134 1/2, weighed 135 1/4 for his December 6, 2013 bout, and, besides fighting lightweights and light welterweights, fought against welterweights and light middleweights.

I was wondering if it was really Alcides Cantero who challenged Yoan Boyeaux for the WPC bantamweight title on Friday, January 3, 2013. Is it possible that Boyeaux's opponent was either Diego Sergio Cantero (Global ID #497370) of Argentina or Nelson Cantero (Global ID #346888) of Colombia instead?

Good question... I don't think either he lost 7.8 kg within 4 weeks... Aldo?
