Shubman Gill was discharged from hospital on Monday evening after recovering from a bout of dengue fever but is most likely to miss the World Cup match against Pakistan in Ahmedabad on Saturday.
The opener was admitted to hospital in Chennai on Sunday night after his platelet count dropped below one lakh.
It is learnt that Gill was admitted to well-known multi-care speciality hospital 'Kauvery' and the Indian team's doctor Rizwan monitored his progress.
He tested positive for the viral infection on arrival in Chennai last week and ended up missing Indian team's World Cup opener against Australia on October 8.
He will also miss Wednesday's game against Afghanistan in Delhi as he is required to rest for at least one more week, which effectively rules him out of match against Pakistan.
He could also miss the match against Bangladesh in Pune on October 19.
"Shubman Gill was on drip at the Chennai team hotel for the last couple of days. His platelet count dropped to 70,000 and he was admitted to a medical facility as a precautionary measure. He was admitted for all mandatory tests on Sunday night when India played Australia but by Monday evening he was discharged," a BCCI source said on condition of anonymity.
A bout of dengue weakens the body considerably and even elite athletes take time to recover completely.
Skipper Rohit Sharma had said that his first priority for him is to see that Gill is no longer sick.
"I feel for him. But in terms of, you know, me being the human being first, I want him to get well, not the captain thinking, oh, I want Gill to play tomorrow. No, I want him to get… well he, you know, he's a young guy he's got fit body so he'll recover he'll recover quick," Rohit has said before the game against Australia.
There is a possibility that the selectors might call up cover for Gill.
The first option will be Ruturaj Gaikwad, who was selected as an opener during the Australia series and also scored a half-century in Mohali.
As per the succession line created, Gaikwad is next but left-handed sensation Yashasvi Jaiswal, who has been in fantastic form, will also be in mix.
