Veteran all-rounder Ravindra Jadeja is unlikely to regain full fitness ahead of the Bangladesh Test series, starting December 14 in Chittagong, according to BCCI sources. With India already having three specialist spinners -- off-spinner R Ashwin, left-arm spinner Axar Patel and left-arm wrist spinner Kuldeep Yadav in their ranks, there is a question mark if a fourth specialist spinner is warranted.

If they seek a straight forward replacement, then it will be Saurabh Kumar, the India A bowler. But there are speculations that new selection committee or Indian team management (in case new committee is not formed by then) could utilise Suryakumar Yadav`s red-hot form and include him in the longer version. India are due to play two Tests and three ODIs in Bangladesh and a full strength team under Rohit Sharma is set to visit the neighbouring nation. India will play two Tests -- December 14-18 in Chittagong and December 22-26 in Mirpur after a short three-match ODI series in the first week of next month. Jadeja had undergone a knee surgery after the Asia Cup in UAE and was then ruled out for an indefinite period.
