Clarke could not play the fourth and final Test match against India due to his back injury.
CA Chief Medical Officer Justin Paoloni was quoted as saying by the CA website: "Michael Clarke had scans that confirmed his current lower back injury is an exacerbation of previous issues he has had with his spine. 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. He also has a hamstring injury that has been a concern for most of the summer and will complicate his return," Paoloni said.
"Michael is having intensive rehabilitation for both his back and hamstring but is still 7-10 weeks away from returning to training and playing. We are confident that it will not affect his Ashes preparation but will know more over the coming weeks," he said.
Clarke plays for IPL side Pune Warriors India.
The IPL 2013 will commence with an Opening Ceremony on the evening of Apr 2 at the Salt Lake Stadium in Kolkata.
The sixth edition of IPL will be played across the country from Apr 3 to May 26.
