How can India bring Kuldeep Yadav into the playing XI?

India's team management is considering the use of Kuldeep Yadav, a left-arm wrist spinner who has not played a game yet. Yadav has been seen turning his arm over for long periods in practice at Kensington Oval. Despite his impressive performance, the nature of the practice pitch and centre-wicket for the upcoming game remains uncertain, but if it is close, Kuldeep should be in the fray.
