Super Flyweight = Vic Darchinyan vs Jorge Acre

Jr Flyweight = Ivan Calderon vs Roman Gonzalez
Minimumweight = No idea i know Roman Gonzalez is a Minimumweight, so him against any of the title holders is interesting, but it would be awesome if he could move up in weight and fight Ivan Calderon.

This is a fantastic match up, should be very entertaining.
