During a press conference on November 19, 2014, Místico announced that he was not ready to return to the ring, which led to the CMLL World Welterweight Championship being declared vacant.

Negro Casas and Máscara Dorada outlasted the other eight competitors; Delta, Fuego, Kamaitachi, Pólvora, Rey Cometa, Sangre Azteca, Titán and Tritón.

A week later Máscara Dorada defeated Negro Casas to become the 29th CMLL World Heavyweight Champion.
