Australia fast bowler James Pattinson has suffered a stress fracture to his lower back and will miss the remainder of the 2013 Ashes series against England.
Pattinson reported soreness in his hip and back following the end of the second Test at Lord's, where he was the last man to be dismissed as his side were beaten by 347 runs.
The 23-year-old will remain with the squad as they head to Hove for a tour match against Sussex before leaving for Australia.
"James Pattinson reported some hip and back soreness on the final day of the second Ashes Test," Cricket Australia team doctor Peter Brukner said.
"We had some scans done today in London that have identified an early stage low back stress fracture. Unfortunately he will not take any further part in this Test series and will commence a rehabilitation program with the aim to have him back for the Australian summer," he added.
Cricket Australia Team Performance General Manager Pat Howard added: "While we are obviously disappointed for James, the selectors have five bowlers fit and ready perform in England, providing them with many options.
"It is also important to note that several players have been performing for Australia A and are available to be called up at any stage if the NSP required them. We’ve been well planned to have as many bowlers fit and available in the lead-up to this important series and while this set-back for James is disappointing, we are confident we have good fast bowling depth."
Pattinson has taken seven wickets in the two matches so far but his absence is another blow for the struggling Australians, who are 2-0 down in the five-match series.
The other fast bowlers in the squad yet to feature in the series are Jackson Bird and James Faulkner although the way in which the pitches at Trent Bridge and Lord's have aided England's spinners may tempt the Australians to add leg-spinner Fawad Ahmed to their squad instead of calling up another replacement quick bowler.
Mitchell Starc, who was dropped for the Lord's Test having played at Trent Bridge, is the other pace bowler who could step up.
Other Australians currently playing county cricket that could join up with the squad include Trent Copeland (Northamptonshire), Steve Magoffin (Sussex) and Michael Hogan (Glamorgan).
More likely contenders would be the likes of Mitchell Johnson, Patrick Cummins or Josh Hazlewood, the latter two of whom are on the 'A' tour of Zimbabwe and South Africa.
