Australia have no plans to rush Ryan Harris back to action until he has fully recovered from knee surgery.
The 34-year-old underwent an operation in March and Australia's bowling coach Craig McDermott says Harris may have to wait until the domestic summer to make his international comeback.
McDermott admits that this October's trip to the United Arab Emirates, for Test and one-day matches against Pakistan, was originally seen a possible return date for Harris who may now have to wait a little longer to wear his country's green baggy cap.
And McDermott said: "He's definitely touch and go for Dubai, we've just got to see how his knee goes over the next few months.
"I don't think there's any point rushing Ryano, we've got a lot of cricket with India, the World Cup, West Indies and the Ashes, we've got to make sure he's 100 per-cent when he comes back."
The Aussies also have serious concerns over another fast bowler, James Pattinson, who has suffered a recurrence of the back problems that have plagued his career.
The 24-year-old missed most of the recent Australian domestic summer but recovered to face South Africa in Cape Town in early March.
However, he has not bowled since with reports that he has suffered further stress to his lower back.
McDermott added: "I want to make sure we take our time and get it right. He's obviously having some sort of trouble with his skeletal makeup that's not coping at his age.
"Patto does bowl fast, so we've got to make sure we get him right and take our time to bring him back nice and slowly."
Australia start their tour of the United Arab Emirates on October 4, when they face Pakistan in two Tests, four ODIs and one Twenty20 international.
