In the co-feature, a welterweight bout is apparently taking place at junior middleweight. Jose Miguel Cotto (31-1-1, 23KOs) moved up by nearly two weight classes to come in at 149-pounds. Unbeaten Saul "Canelo" Alvarez (31-0, 23KOs) weighed 150-pounds. Something tells me Alvarez had trouble making the weight.

Announced to the stage were such fighters as Juan Manuel Marquez, Andre Berto, Joe Calzaghe, Ricky Hatton and Sergio Mora.
