The co-main event featured former world champions Javier "El Abejón" Fortuna (35-2-1, 24 KOs) from the Dominican Republic knocking out Argentina's Jesús Andrés Cuellar (29-4, 22 KOs) at the 2:01 mark of the second round in their super featherweight showdown. Fortuna knocked down Cuellar in both the first and second stanzas. Shortly following the second knockdown, the referee had seen enough, calling a stop to the action.
