"If I am needed on Wednesday, then I will be ready to go. I feel in good rhythm. I am in a good place," said Finn, who bowled six overs in two spells at the nets Monday without discomfort.
Finn, who has 66 wickets in 16 Test matches, suffered a thigh strain in the first warm-up game of the tour and there was concern he might miss the entire series. However, he recovered in time for the Kolkata test.
"If I am picked as part of a two-man seam attack, I might be used in a strike-bowling capacity. In the subcontinent you need to have a degree of patience and use your skills wisely," said Finn.
With fellow pacer Stuart Broad yet to get a wicket in the series and bowling coach David Saker describing his form as an "issue", Finn might find favour of the selectors in the upcoming match.
"India has a great batting line-up and to get the wicket of somebody you have admired as you grew would be quite a big thing," said Finn on his aspiration to get the prize wicket of batting maestro Sachin Tendulkar.
