James Pattinson will miss the Indian Premier League after suffering another setback which also threatens his participation in June's Champions Trophy.
He is set to undergo abdominal surgery which will put him out of action for around four weeks, although Cricket Australia (CA) are optimistic that he will be fit in time for the Ashes.
Pattinson missed the end of Australia's summer with an injury to his left lower rib cage, and had previously missed much of the 2011-12 season with a foot problem.
"James Pattinson will be having surgery tomorrow for a non-cricket related medical condition in his lower abdominal region that has been troubling him during the latter part of the recently concluded VB Tour of India," CA Chief Medical Officer Justin Paoloni confirmed.
"James has undergone tests and consulted specialists since returning from India, and it was felt that surgery is absolutely necessary at this time.
"The recovery times will determined once the surgery is completed but James is expected to return to training in approximately 4 weeks. His preparation for The Ashes is not expected to be affected but his availability for the ICC Champions Trophy will be determined at a later stage."
He had been set to play for reigning champions Kolkata Knight Riders in the Indian Premier League 2013.
