South Africa captain Graeme Smith's participation in the second and final Test in Kolkata is in doubt after he injured his finger during training at the Eden Gardens in Kolkata, on Friday.
Smith was undergoing catching practice in the morning when he hurt his little finger on the left hand. He was immediately rushed to a local hospital.
An MRI scan confirmed ligament damage and there is considerable swelling around the injury.
South Africa's medical team expressed confidence that the swelling will subside in the next 24 hours and Smith will put his finger to the test during Saturday's practice, after which a decision on his fitness will be taken.
South Africa lead the series 1-0, having won the first Test by an innings and six runs.
