A Brazilian radio report says former Fifa president Joao Havelange has been hospitalised in Rio de Janeiro.
Radio Band News says the 95-year-old Havelange was admitted to the Samaritano Hospital late Sunday night.
The cause of his hospitalisation is however yet to be ascertained as neither his spokesman nor the hospital was available to comment on the issue.
Late last year, Havelange resigned from the International Olympic Committee citing undisclosed health reasons. The resignation came while he faced a possible suspension for allegedly taking kickbacks from former Fifa marketing partner ISL in the 1990s.
Havelange presided over FIFA from 1974-1998, when he was replaced by current president Sepp Blatter.
