A scan has revealed that Australia captain Michael Clarke batted with a fractured shoulder during the third and final Test against South Africa in Cape Town.
Clarke bravely resisted hostile spells of bowling on his way to a century that helped his side secure a 2-1 series win.
Australia won the match by 245 runs after Clarke had made an unbeaten 161 in 301 balls in the first innings.
However, the fracture means he has been ruled out of the Sheffield Shield final, where he had hoped to be available for New South Wales.
"Michael Clarke was injured as a result of being struck on the left shoulder during the third Test against South Africa in Cape Town," Cricket Australia physiotherapist Alex Kountouris confirmed.
"We have since done a series of scans that have demonstrated a fracture near his shoulder joint.
"We expect that this will heal with a period of rest.
"Michael is therefore unavailable for the Bupa Sheffield Shield final to be played later this week."
New South Wales will play Western Australia in the five-day final, which begins on 21st March.
The tour, while successful for an Australia side that also won the Twenty20 series 2-0, has come at a cost in terms of injuries.
As well as Clarke now facing some time on the sidelines, Ryan Harris has undergone knee surgery that ruled him out until October and Mitchell Johnson has been forced to miss the ICC World Twenty20 due to a toe infection.
