Rohit Sharma has not been included in any of the three squads for India's tour of Australia after he picked a hamstring injury in the ongoing IPL. KL Rahul and Kuldeep Yadav have returned to India's Test squad and uncapped fast bowler Mohammed Siraj has also been called-up for the four-match series in December-January.
Ishant Sharma's injury in the IPL meant he was not in the Test squad either, and the BCCI has said in a statement they will "continue to monitor the progress of Rohit Sharma and Ishant Sharma."
While Rohit picked up a hamstring injury last week and he is still in the UAE with the Mumbai Indians squad, Ishant was ruled out of the IPL much earlier with an abdominal muscle tear and he had returned to India. Ishant has been at the National Cricket Academy in Bengaluru since then.
