New Delhi:Australia pacer Michael Neser has sustained a right calf strain during a training session. The blow delayed his preparations for the upcoming South Africa series in October. Australia's training camp in Brisbane has otherwise produced few injury concerns. Cummins, Hazlewood, Mitchell Starc and Scott Boland have all come through preparations without issue, while Nathan Lyon has bowled extensively after returning from hamstring surgery. Green and Beau Webster are both expected to feature in the first Test, with Green a likely option at No.
