Silgado turned pro with twelve straight knockouts before winning the World Boxing Association (WBA) Fedecaribe and Colombian Cruiserweight titles with a third round stoppage over Jose Chiquillo.
He defended the WBA belt once before capturing the WBA Fedebol title with a unanimous decision victory over Sergio Martin Beaz.
In his last bout, Silgado stopped Cesar Dairo Herdia in one round on January 24, 2009.
“This is a big signing for us”, said Robert Diaz, Promoter for Havoc Boxing.
“We have had two great events in the past few months and the signing of Silgado shows that we are looking throughout the world for the best talent and we feel he can be a major force in the cruiserweight division. He is a young man with lots of power and he will be featured on our next show”
