The knee injury of Yuvraj Singh will be reassessed after two weeks by Dr Anant Joshi, the Board of Control for Cricket in India's medical consultant who examined the player at Lilavati Hospital in Mumbai on Monday.

Yuvraj, who was provisionally included in the Indian one-day squad announced today for the South Africa tour, has been advised to follow some exercises and use crutches to take the load off the injured part of his body.

"According to Dr Joshi, there is a tear in the interior cruciate ligament with some amount of bruising of the bone in the left knee and there is a swelling of the knee," a BCCI statement said.

"The doctor has recommended some exercises and Yuvraj Singh has been advised to use crutches to take the load off the knee," it said.

The condition of "Yuvraj Singh's knee will be re-evaluated after two weeks for further line of action," it said.

Yuvraj sustained the injury on the eve of India's crucial Champions Trophy Group A league match against Australia at Mohali, where the hosts bowed out of the competition.

The injury occurred when the team members played kho-kho as a warm-up exercise prior to the net session and he had to be helped off the field.
