Nathan Hauritz and Mike Hussey are set to miss the World Cup after Cricket Australia confirmed they had applied to replace them in their 15-man squad.
Spinner Hauritz has a dislocated shoulder and middle-order batsman Hussey has a hamstring injury, and, although they were both named in the party to travel to the sub-continent, they are now set to be replaced by Jason Krejza and Callum Ferguson.
Krejza made his one-day debut in Sunday's win over England in Perth and benefits from an injury to second-choice spinner Xavier Doherty, while the absence of Shaun Marsh means Ferguson has got the nod to replace Hussey.
Commenting on the decision to request the changes, chairman of selectors Andrew Hilditch said: "During the Commonwealth Bank Series we had a number of injuries to prominent players in our World Cup squad.
"Specifically, both Mike Hussey and Nathan Hauritz suffered significant injuries both of which necessitated surgery.
"The National Selection Panel has received a full briefing from CA medical staff. Based on the medical advice an application is being made to the ICC to replace both players in the World Cup squad."
There is better news for captain Ricky Ponting, though, with physio Alex Kountouris confirming his broken finger is healing according to schedule, while Brad Haddin (knee) and Steve Smith (groin) are both expected to recover in time.
