LUCKNOW, Sept. 12 -- Two key Australian players have been ruled out of the Australia A tour to India beginning September 16 (Tuesday) with the first four-day encounter at the Atal Bihar Vajpayee Ekana Cricket Stadium here. The second four-day game against India A starts on September 23 whereas the three one-dayers, which will all be played in Kanpur, are on September 30, October 3 and 5. While allrounder Aaron Hardie has been ruled out due to a shoulder injury, Queensland teenager Callum Vidler will not be part of the visiting team due to a partial stress fracture. Hardie will be replaced by Victoria allrounder Will Sutherland, who was already part of the one-day squad for the tour and will fly out to India in time for the second four-day game in Lucknow. A replacement for Hardie in the one-day squad will be named at a later date. According to a report, it is hoped that Hardie will be able to recover in time for the early rounds of Sheffield Shield matches-Western Australia's opening game is against New South Wales at the WACA on October 4. Hardie featured in the recent T20I and ODI series against the West Indies and South Africa but he struggled against the latter and had not been selected for the short New Zealand trip for three T20Is but was included in the A squad. Depending on how his recovery tracks, he may be considered for the white-ball series against India. Though an allrounder rather than a specialist bowler, Hardie's injury adds to a growing list of players sidelined heading into the season. Pat Cummins is the most significant with question marks over whether he will recover from his back injury in time for the Ashes, the report adds. Lance Morris, a team-mate of Hardie's at WA, has been ruled out for 12 months having undergone back surgery, while promising quick Callum Vidler has been detected with a stress fracture. Morris had been due to feature in the four-day leg of the A tour and Vidler the one-dayers. Brody Couch had initially been Morris' replacement but he suffered a side injury during the Top End T20 final with South Australia's Henry Thornton subsequently called up.
