New Delhi, Nov 22 (PTI) 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.<br> 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. <br> If they seek a straight forward replacement, then it will be Saurabh Kumar, the India A bowler.<br> 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.<br> 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.<br> 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.<br> Jadeja had undergone a knee surgery after the Asia Cup in UAE and was then ruled out for an indefinite period.<br> "Jadeja has been to NCA for his check-up and rehab on a number of occasion. However as of now, it is unlikely that he will be fit for the Bangladesh series. In any case, Chetan Sharma-led former selection committee had kept him in the squad subject to fitness," a BCCI source privy to developments told PTI on conditions of anonymity.<br> There is still some time to announce the replacement.<br> Saurabh has been a part of the Test squad during the series against Sri Lanka earlier this year. He also got a five-for against New Zealand A in an 'A' Test series in Bengaluru.<br> But second option could be an adventurous one as Ashwin, Kuldeep and Axar's presence makes it difficult to select a fourth spinner.
