The Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG) first held a professional wrestling supercard called El Gran Desafío ("The Great Challenge") on July 2, 2009 in their home arena Arena Naucalpan.
The main event featured IWRG-mainstay Dr. Cerebro against internationally known wrestler Juventud Guerrera in a best two-out-of-three falls Lucha de Apuestas, hair vs. hair match.
[1] Three months later IWRG held another Gran Desafío show, this time titled El Gran Desafío Femenil – Sin Empate, Sin Indulto (Spanish for "The Great Women's Challenge – No draws, no reprieve") which featured a rare for IWRG women's wrestling main event as Flor Metálica defeated Atsuko Emoto in a Lucha de Apuestas match, forcing Emoto to have her hair shaved off.
