Ahmedabad: Indian skipper Mahendra Singh Dhoni said that the devastating opener Virender Sehwag is doubtful for the quarterfinal clash against defending champions Australia at Motera, Ahmedabad.

"We will take a call on Virender Sehwag before the start of the game. All the others are fit and available for selection," Dhoni said in a press conference.

Sehwag, who lit up the tournament with a breathtaking 175 against Bangladesh in the opening match at Mirpur on February 19, missed India's last Group B tie against the West Indies at Chennai on March 20 after aggravating his old knee problem during the course of the tournament.

He played last against South Africa at Nagpur on March 12, scoring a half century.

Dhoni said the Indian team would certainly miss Sehwag if he is unable to play tomorrow against the world's top-ranked ODI outfit.

"It's really good to have Virender Sehwag opening the innings. He can play an aggressive game. He can change the course of the game in the first five overs, give the team the kind of momentum that is needed," said Dhoni.

Yesterday, the Delhi dasher did not take part in the warm-up session but later joined the team in the batting practice for half an hour.
