HATERS GONNA HATE TMZSports.com
Former boxing champion Fernando Vargas is calling out anyone criticizing his sons' boxing careers ... telling TMZ Sports they're bold behind a keyboard, but don't have the guts to say any of it to their faces!!
Vargas' three sons are all boxers ... including Amado, who has a fight on Saturday against Angel Luna at the Gateway Center Arena in Atlanta.
Vargas is confident his son will secure his 13th straight win by knockout in "four, five rounds" and maintain his perfect record.
