Australia seamer Ryan Harris has undergone surgery on his injured knee and now faces a race against time to be fit October's tour of India.
The 30-year-old suffered the injury during the fifth one-day international against England at Lord's last week, and immediately returned to Australia.
That meant he missed the upcoming Test series with Pakistan and is also doubtful for the two-Test and three-ODI series against India, which begins on October 2.
"Ryan Harris underwent arthroscopic surgery in Melbourne on Thursday to correct cartilage damage to his right knee," Cricket Australia doctor Trefor James said.
"His progress will be monitored in the coming weeks to determine his availability for selection for the VB Tour of India tour in October."
Harris' injury continues a run of woes for Australia's pacemen, with Peter Siddle and Brett Lee both sidelined for long periods, while Ben Hilfenhaus made his return after seven months out with a knee problem in the recently-completed tour match against Derbyshire.
