Shaun Marsh will next week learn the seriousness of the shoulder injury which has cut short his county season in England and left Australia with potentially another major hole in its batting line-up.
Already with headaches after the poor one-day international campaign in England, selectors now face a nervous wait to find out what ramifications Marsh's injury will have for Australia's series in the Middle East against Pakistan.
The veteran batsman is due to have further scans when he arrives home from England after hurting ligaments in his left AC joint in the field for Glamorgan in a Twenty20 match.
The schedule for the Pakistan Tests has not been finalised but is expected to take place in October, followed by a Twenty20 series.
Australia can ill afford to lose a player of Marsh's experience for the series, the Test team's first since the ball tampering affair which resulted in Steve Smith, David Warner and Cameron Bancroft being handed lengthy bans.
Of those in line to bat in the top six, only Usman Khawaja, whose record against spin means he is no lock to keep his place, has played more Tests than the West Australian.
Marsh is also one of the country's best players of slow bowling, which will be vital on the likely spin-friendly tracks in the UAE, where a stronger and more experienced Australian team was thrashed 2-0 under Michael Clarke in 2014.
Already touted as a Test trial, the Australia A tour of India will take on even greater importance if Marsh was to be ruled out to play Pakistan.
Mitchell Marsh needs to prove his fitness while Khawaja, Peter Handscomb, Matt Renshaw and uncapped pair Travis Head and Kurtis Patterson can all press their claims with strong performances on the subcontinent.
There are several bolters who can leap up the World Cup pecking order for the one-day component of the Australia A series.
The 5-0 whitewash has given selectors the mandate for change for Australia's next series, which will be at home against South Africa in November.
Head and D'arcy Short are facing challenges from Handscomb, Khawaja, Renshaw and unheralded Queensland batsman Marnus Labuschagne.
Gloveman Alex Carey, named as vice-captain for the tour, will place further pressure on skipper Tim Paine's ODI spot if he fires.
Paine has acknowledged his position in the side, and by association the captaincy, was under scrutiny after a lean series with the bat.
Coach and selector Justin Langer hinted change was on the cards when he praised Aaron Finch for his form as skipper in the Twenty20 tri-series against Zimbabwe and Pakistan.
There is better news for Australia with its trio of star fast bowlers, who are all on the comeback trail from injury.
Mitchell Starc is due to resume bowling in the coming days having not played since breaking down with bone stress in his right leg. The injury prevented him from playing in the Indian Premier League.
Josh Hazlewood is expected to be back bowling by the end of the month. The giant quick is recovering after being diagnosed with "low level bone stress" on the eve of Australia's departure for England in May.
Pat Cummins, the furthest behind of the so called Big Three, will have scans at the end of the month on his injured back to determine when he can resume bowling. His recovery, however, is said to be going as planned.
