Triple Olympic hockey gold winner Leslie Claudius's son Brandon said that Leslie who was suffering from cirrhosis of the liver, was admitted to a private hospital following complications.
"He was shifted to a hospital last night following some complications. His condition is critical," Brandon said.
The 85-year-old is currently being treated at the Intensive Care Unit (ICU) of the hospital near the Eastern Metropolitan bypass in the city's southern outskirts.
Following abnormal fluid retention, Claudius was admitted Oct 27 to another hospital before being discharged Saturday.
In the last 11 months, Claudius has been hospitalised four times.
Claudius has three Olympic gold medals - London 1948, Helsinki 1952 and Melbourne 1956. At Rome in 1960, he led India to a silver medal finish.
