Brazil legend Pele is in hospital after undergoing back surgery.

Calls to Pele’s personal assistant, Jose Fornos, for details went unanswered.

Known as “O Rei” (The King), Pele was admitted on Tuesday, but his family did not authorise the hospital to reveal the reason for the operation, Globo Esporte said.

SAO PAULO (AP) – A Brazilian hospital says Pele is hospitalized in Sao Paulo.

The statement did not say when 74-year-old Pele is expected to be discharged from the hospital, but news reports indicated it would be sometime in the coming week.

The doctors then said the condition detected was “benign” and there were no tumours. Tests conducted after that surgery showed there were no tumors.

This is the third time Pele has been hospitalised since November, when he spent two weeks at the Einstein facility with kidney problems.

With more than 1,280 career goals and an unequaled three World Cup titles during his playing career, Pele is considered by many to be the greatest soccer player of all-time.
