Tendulkar – widely considered the greatest batsman of all time – said he had mild symptoms in a tweet on Saturday.
“I’ve quarantined myself at home and am following all the necessary protocols as advised by my doctors,” he wrote.
The former India captain, 47, shared his diagnosis as the country grapples with a surge in coronavirus infections.
India recorded 59,118 new infections on Friday, the highest 24-hour rise so far this year. Many of the new cases were reported in the western state of Maharashtra, where Tendulkar lives in the city of Mumbai.
