Australia captain Michael Clarke is months away from returning to training as he overcomes persistent back and hamstring issues, Cricket Australia said on Tuesday.
Clarke has been assessed after returning last weekend from the India tour and has had scans of his injuries, CA said.
He was due to take up the captaincy of Indian Premier League side Pune Warriors but will instead recover at home. CA said it was confident Clarke would lead Australia in the Ashes Test series in England in July.
"Michael Clarke had scans that confirmed his current lower back injury is an exacerbation of previous issues he has had with his spine," CA Chief Medical Officer Justin Paoloni said in a statement.
"As always, we need to manage this carefully as there are potentially serious consequences with further aggravation.
"He still has pain with basic activities and is not back to full function as yet."
Paoloni said hamstring problems will also complicate Clarke's return to cricket.
"Michael is having intensive rehabilitation for both his back and hamstring but is still 7-10 weeks away from returning to training and playing," he said.
"We are confident that it will not affect his Ashes preparation but will know more over the coming weeks."
CA said Clarke's rehabilitation programme would be overseen by the organisation's medical team and back specialists.
Clarke was the only batsman to perform consistently in the Test series Australia lost 4-0, scoring 286 runs at an average of 47.66.
The first Ashes Test begins at Nottingham's Trent Bridge ground on July 10.
