Uruguay's home stadium is the Estadio Centenario, and they have been coached by Marcelo Bielsa since 2023.

The Brazil national football team, nicknamed Seleção Canarinho, represents Brazil in men's international football and is administered by the Confederação Brasileira de Futebol, the governing body of football in Brazil.

The match between Uruguay and Brazil was the decisive match of the final stage at the 1950 FIFA World Cup. It was played at the Maracanã Stadium in the then-capital of Brazil, Rio de Janeiro, on 16 July 1950.

The 1950 FIFA World Cup was the 4th edition of the FIFA World Cup, the quadrennial international football championship for senior men's national teams. It was held in Brazil from 24 June to 16 July 1950. It was the first World Cup tournament in over twelve years, as the 1942 and 1946 World Cups were cancelled due to World War II. Italy, the two-time defending champions, were eliminated in the first round for the first time in history. Uruguay, who had won the inaugural competition in 1930, defeated the host nation, Brazil, in the deciding match of the four-team group of the final round, causing what is sometimes known as one of the biggest upsets in sports history, occasionally called the Maracanaço. This was the only tournament not decided by a one-match final. It was also the inaugural tournament where the trophy was referred to as the Jules Rimet Cup, to mark the 25th anniversary of Jules Rimet's presidency of FIFA.
