Overview
The term "behind closed doors" is used in several sports to describe matches played where spectators are not allowed in the stadium or venue to watch. The reasons for this may include punishment for a team found guilty of a certain act in the past, stadium safety problems, public health concerns, or to prevent potentially dangerous clashes between rival supporters
Crowdless games are a rare occurrence in professional sports. When they do occur, it is usually the result of events beyond the control of the teams or fans, such as weather-related concerns, public health concerns, or wider civil disturbances unrelated to the game. For instance, the COVID-19 pandemic caused most sports leagues around the world to be played behind closed doors.
Examples
Brazil
In Brazil, the practice of games without public access is known as "closed gates" (in Portuguese, portões fechados), even referred as such in the Brazilian Football Confederation's rulebook. Once it was applied to a whole tournament: two rounds of the Campeonato Catarinense second division in 2014 were behind closed doors because the competing clubs did not deliver the security checks for their stadiums. Sanitary reasons dictated the restriction in 2009, where two games of the Série D were played behind closed doors due to the H1N1 flu pandemic.
