Rios' most high profile bouts were losses to Freddie Norwood, Miguel Callist and more recently against WBC 154 lbs titleholder Javier Castillejo in a ridiculous jump up in weight. In his last bout, Rios was knocked out in three in Managua against Jose Alfaro. Ngoudjo holds a TKO victory over ex-world champ Eloy Rojas in February.
On the same card, Canadian heavyweight champion Patrice L'Heureux will try to rebuild his confidence, which was brutally severed in a shocking first round KO loss to unheralded Steve Pannell a month ago. The very entertaining junior middleweight Walid Smichet (9-1-2, 7 KOs) has also been confirmed for this show, although L'Heureux and Smichet's opponents are not yet known.
