Clarke watched the first day's play of the final Test today from the Australian dressing room but will not be around tomorrow as he has been advised a series of tests on his back and a hamstring complaint that affected him during the summer.
Clarke has been battling a degenerative disc condition since he was 17 and will be assessed by medicos to ensure he is at peak fitness for the Champions Trophy in June before the Ashes showdown in England.
"The plan is for Michael to return to Sydney as soon as possible to have a series of scans and we will monitor his progress over the coming days before deciding on the best course of action," Kountouris was quoted as saying by the Australian media.
"We will be taking the opportunity to investigate and manage his ongoing hamstring injury that has been intermittently troubling him since the Australian summer. A decision on his return to cricket will be made once we have evaluated the scans and considered the possible management options."
