The hospital spokeswoman said on Tuesday in Rio de Janeiro, that the 100 year old Havelange, had been admitted last month to the Samaritano hospital in the Botofoga district of the city for treatment for pneumonia.
Havelange was president of FIFA from 1974 to 1998 during which he was one of the most influential figures in international sport.
He was a former Olympian swimmer and water polo player who was president of the Brazilian Sports Confederation during the most successful periods of the country’s football.
The former FIFA boss was also a member of the International Olympic Committee (IOC ) for more than four decades.
Havelange was the subject of corruption investigations and it was alleged by Swiss prosecutors in July 2012 that he and his son-in-law Ricardo Teixeira took tens of millions of dollars in bribes in connection with the award of World Cup marketing rights.
