brother team of Dr. Wagner Jr. and Silver King defeated Dos Caras and Último Dragón to become the seventh overall champions. Tournament bracket August 1997 The team of Silver King and Dr. Wagner Jr. had held the championship since winning a tournament on February 2, 1997, but in August, 1997 Silver King left CMLL to work for Promo Azteca and the U.S. based World Championship Wrestling (WCW). CMLL held a two-night, eight-team tournament to fill the void left by Silver King leaving. The finals took place on August 29, where Dr. Wagner Jr. and his new partner Emilio Charles Jr. defeated Los Headhunters to become the eight overall champions. Tournament brackets 1998 In the fall of 1998 Mr. Niebla suffered an injury while holding the CMLL World Tag Team Championship with Shocker. Due to the injury Mr. Niebla was unable to compete so CMLL declared the championship vacant and put together an eight-team tournament to crown new champions. The tournament started on October 30 and lasted until November 13 where the team of Bestia Salvaje and Scorpio Jr. defeated El Satánico and Dr. Wagner Jr. to become the tenth over all tag team champions. Tournament brackets 2000 On June 16, 2000, the CMLL World Tag Team Championship was announced as vacant. The official explanation was that co-champion Negro Casas voluntarily gave up the championship to "give other teams a chance", but in reality his partner, El Hijo del Santo, had stopped working for CMLL. CMLL organized a 16-team tournament from June 23 through August 4, 2000, with the finals being at CMLL's Entre Torre Infernal pay-per-view. The finals of the tournament was set to be Los Infernales ("The Infernal Ones"; Rey Bucanero and Último Guerrero) against the team of Emilio Charles Jr. and Mr. Niebla but Emilio Charles Jr. had suffered an injury before the show began. As a result, Los Infernales were declared the new champions. The team was then ordered to defend the championship against Mr. Niebla and his new partner Villano IV so there was still a championship match on the show. Los Infernales retained the championship. They later successfully defended against Mr. Niebla and Emilio Charles Jr. on August 18, 2000.
