Indian women's cricket team captain Harmanpreet Kaur is doubtful for the deciding game of the India v West Indies T20 series on Thursday.

Harmanpreet was sidelined from the second game after she suffered a niggle in her knee during the first game.

Her deputy, Smriti Mandhana said that the team is awaiting an update on Kaur's availability for the third match.

"Harman's fitness, (the) BCCI medical team is observing on a day-to-day basis. They'll be in a better place to answer that question. I think we'll have to wait for the update from their side," Mandhana told media after India's crushing nine-wicket loss here on Tuesday.

Kaur, who turned up for practice here last Saturday with her knee strapped, scored 13 not out in India's big total of 195/4 but she did not take the field in the series opener here.

"Harmanpreet Kaur sustained a niggle in her knee while batting during the first T20I against West Indies. Hence, she remains unavailable for selection for the second T20I. The BCCI Medical Team is monitoring her progress," the team issued a statement ahead of the second T20I here.

Mandhana, meanwhile, brushed aside any concerns regarding her after she copped a blow to her hand towards the end of the second match.

"I think (the) finger is fine now. Just that initial impact, where you think that 'oh, it can be wrong', but it's all good now," Mandhana said.

India won the first match against West Indies but lost the second game making the final game a decider to win the series.
