The first indications of who would be involved in the 2009 "Infierno en el Ring" cage match came when Naito commented that one of his goals while working in Mexico was to win the hair of Héctor Garza. On July 10, 2009 Black Warrior made a challenge to Héctor Garza on behalf of Naito, since he did not speak Spanish. Shortly after the challenge it was announced by CMLL that nine wrestlers would participate in cage match: Naito, Yujiro, Black Warrior, Shocker, El Texano Jr., Negro Casas, El Terrible and Tarzan Boy but not Héctor Garza.
