India all-rounder Yuvraj Singh is likely to sit out of the second semi-final of the ongoing World T20 against the West Indies on Thursday due to an ankle injury. According to sources, the team management are sweating over the various options they have on the bench, including batsman Ajinkya Rahane and all-rounder Pawan Negi. (Yuvraj Singh’s injury puts focus back on Ajinkya Rahane ) Sources say, while manager Ravi Shastri wants Rahane to replace Yuvraj in the middle order, captain Mahendra Singh Dhoni is gunning for left-arm spinner Negi. Manish Pandey too has arrived in Mumbai as cover for Yuvraj. Pandey could be the dark horse because of his heroic hundred that helped India beat Australia in the last of a five-match ODI series at the Sydney Cricket Ground earlier this year. Rahane has not found favour with Dhoni in limited-overs cricket and while the captain had spoken highly of Negi, who is an able batsman down the order and is more than handy with his slow left-arm spin.
