About the article "Wrestling", section "Lucha libre".

Candidate passages:
Mexican professional wrestling, also known as "Lucha libre" is a style of wrestling that combines mixed-martial arts and the wrestling of North America.
In Lucha libre the wrestler or "luchador" uses a mask to cover his face.
Traditionally the match is for the best of three rounds without a time limit.
The "Luchador" or "wrestler" athlete uses their own wrestling style or "estilo de lucha" consisting of aerial attack wrestling moves, strikes and complex submission moves.
The most popular "luchadores" are Santo, Blue Demon, Rey Mysterio, Eddie Guerrero, La Parka, Dos Caras Jr./Alberto Del Rio and Mistico.
Mexican professional wrestling, which is known as lucha libre, has been a popular sport in Mexico since 1933, when promoter Salvador Lutteroth Gonzales founded Empresa Mexicana de Lucha Libre.
Like other forms of professional wrestling, it is not strictly a sport, as matches usually have predetermined outcomes.
Lucha libre is characterized by rapid sequences of holds and moves, as well as spectacular high-flying moves, many of which have been adopted in the United States.
The two most popular lucha libre promotions are Consejo Mundial de Lucha Libre (CMLL), and Asistencia Asesoría y Administración (AAA).
Wrestling stars include El Santo, Blue Demon, and Mil Máscaras.
Lucha libre is currently experiencing a boom in popularity due to the emergence of a new generation of stars, most notably a young wrestler named Místico, whose high flying style is attracting record crowds. 
Unlike most sports or sports entertainment around the world "Lucha Libre" holds championships in less regards compared to the prestige of winning a "Lucha de Apuesta", literally a "bet match".
In a "Lucha de Apuesta" match each competitor "Bets" either their wrestling mask or hair on the outcome of the match and if they lose must unmask or have their hair shaved off in the ultimate form of humiliation.
Since the mask holds a sacred place in "Lucha Libre" the most prestigious "Apuesta" is the mask, once it is lost a wrestler is not allowed to put the mask back on when wrestling.
As part of the tradition an unmasked wrestler must also reveal their "true identity", which means give their birth name, age and wrestling experience as they lose the "anonymity" of the "enmascarado" character.
Over the years Arena Coliseo has been host to a number of "Luchas de Apuestas", including one that many consider the biggest "Luchas de Apuestas" match where "Lucha Libre" icon El Santo defeated and unmasked Black Shadow in 1952.
Below is a list of all documented "Luchas de Apuestas" that have taken place in Arena Coliseo since its completion in 1943.
