Kolkata, Aug 13 - With only three days to go for the selection of the Indian cricket squad for the Sri Lanka tri-series, uncertainty still looms over Delhi dasher Virender Sehwag. Skipper Mahendra Singh Dhoni failed to confirm Thursday whether the injured opener would be available for the tour.

Sehwag is now undergoing rehabilitation after his shoulder surgery in June and skipped the pre-season fitness camp in Delhi.

'He (Sehwag) is improving every day. He is getting ready for the Champions Trophy. But whether he will be available for the Sri Lanka series, it will be too soon to say right now,' Dhoni said at a press conference held for the forthcoming Kolkata Fashion Week here.
