SAO PAULO -- Pele has been admitted to hospital for a "medical evaluation" after cancelling a planned appearance at an event in his museum.
The Albert Einstein hospital did not disclose why Pele had been admitted, saying in a statement on Wednesday evening that he would "undergo exams."
The private Agencia Estado news service and other local media reported that the 74-year-old was suffering from stomach pain, but that his condition was not serious.
Earlier in the day, the city of Santos said Pele had cancelled his appearance at the Pele Museum in Santos because of "health reasons."
It was not clear how long Pele would remain in hospital, and no further details were immediately available.
