India skipper Mahendra Singh Dhoni [ Images ] said he is not sure of Gambhir's availability for the match.

"As far as injuries goes Gautam is having a problem with either the left or right knee. I am not 100 per cent sure which knee. So we will take a call may be in the evening or tomorrow morning before the game," Dhoni said.

Sri Lanka's fast bowler Lasith Malinga [ Images ] has also been ruled out of the match due to a knee problem.
