Zaheer Khan could miss the rest of India's Test series against England due to injury.
The bowler pulled up on the first day of the first Test at Lord's yesterday with a hamstring problem.
Prior to the injury, the Indian was the key man of the visitors' attack, taking the wickets of openers Andrew Strauss and Alistair Cook.
An Indian spokesman said last night that the injury was being analysed and that a decision would be made today over his participation.
After rain ended the day's play England were 127-2, with Jonathan Trott hitting an unbeaten 58.
