The 49-year-old was admitted in Kolkata on Monday after he tested positive for the virus and was suffering from a mild fever.

"He expressed his desire to go home after he tested negative for the Omicron variant," the doctor told AFP.

His brother Snehasish told AFP that Ganguly received an "antibody cocktail therapy" as part of his treatment.

"Sourav is resting at home," he said.

One of India's most popular players ever and the head of the country's cricket board, Ganguly was twice admitted to hospital earlier this year with chest pain and underwent an angioplasty.

India, where Covid infection numbers have fallen sharply since a devastating surge in April and May, has so far confirmed 1,270 Omicron cases.
