The third-tier professional football league in Brazil is called the Campeonato Brasileiro Série C, or Brazilian Serie C. Here are some details regarding the contest:
Format: The Brazilian Football Confederation (CBF) oversees the Campeonato Brasileiro Série C. 20 teams from various Brazilian states are represented, split into two groups of 10 teams each. Each team in the competition plays every other team in their group twice, once at home and once away, in a double round robin style. The top four teams from each group proceed to the knockout stage after the group stage.
Promotion to the Campeonato Brasileiro Série B, Brazil’s second-tier league, is given to the top four teams from the knockout stage. The teams that place in the bottom four of each group are demoted to the fourth-tier league, Campeonato Brasileiro Série D.
Relegation: For the following season, the bottom four teams from each group are dropped to the Campeonato Brasileiro Série D.
The Taça de Bronze, which had previously served as the third-tier competition, was replaced by the Campeonato Brasileiro Série C in 1981. Several teams have had success in the tournament over the years and have been promoted to higher divisions.
Famous Teams: The Campeonato Brasileiro Série C has featured numerous historic Brazilian football clubs, such Botafogo-SP, Paysandu, Remo, Cricima, Fortaleza, Santa Cruz, and others. These teams have a sizable fan base and have experienced success in the competition.
Television coverage: In Brazil, both national and regional sports networks frequently air matches from the Campeonato Brasileiro Série C.
