A back problem could see Indian strike batsman Virender Sehwag miss the opening match of the one-day series with England in Delhi.
Sehwag suffered the back problem during the third Test and had to use a runner when batting on the final day of the match.
He faces a full fitness test during nets on Sunday.
The home side is already facing the series without Sachin Tendulkar who flew to London to have shoulder surgery.
India's secretary of its board of control Niranjan Shah told BBC Sport: "Sehwag has significantly improved with respect to his back injury.
"He is confident of being available for the first ODI. His clinical signs are presently very promising," he said.
With his one-day strike rate of 97, Sehwag is a key performer for the side.
Meanwhile, Tendulkar, who has been experiencing pain when throwing the ball in the field, has allayed concerns over his future.
"If you look at things in proper perspective, I played just three innings in Pakistan and four at home against England. It is fine. Nothing to be concerned about, he said.
