HYDERABAD - David Warner was a notable absentee from Australia's practice session in Hyderabad on Thursday, struggling again with a bout of gastro. Warner also suffered from gastro during Australia's second innings of the first Test in Chennai and batted at No.3 instead of taking his regular opening spot. The rest of the squad had its first training session in Hyderabad and were greeted by a pitch that bore a few small cracks and a hint of grass.
