If things improve dramatically over the next couple of days, Gambhir ought to be targetting the one-day game against Leicestershire on 29 August after which the Twenty20 and five one-day internationals against England would be played.
However, things are looking far from rosy as the Delhi opener is having trouble fixing his sight on anything -- be it looking at the mobile or watching the television.
Gambhir took to indoor nets at Hove county cricket ground for 45 minutes yesterday. Bowling coach Eric Simmons was at hand to look at his progress.
To onlookers though it was apparent he had trouble in picking up the line and length of throwdowns which Simmons hurled at him.
During the innings break in the match between Sussex and the Indians, Gambhir came out and tested himself with a run in the ground with the Indian support staff trying to assess his fitness.
Apparently, Gambhir suffers from a nausea whenever he tries to exert himself either physically or when he fixes his eye on anything.
The left-hander is suffering from blurred vision after the concussion he suffered while fielding in the final Test at Oval last week. The one-off Twenty20 match is scheduled to be held on 31 August while the first one-day international will be staged in Durham on 3 September.
