South Africa are confident that pace spearhead Dale Steyn will be fit in time to lead the attack against Australia next month.
Cricket South Africa have confirmed that Steyn suffered a fractured rib when landing awkwardly while fielding in the second Test against India two weeks ago.
The paceman defied the pain to claim nine wickets as the Proteas clinched the two-Test series with a 10-wicket victory.
The extent of Steyn's injury was unclear until scans revealed a small fracture of one rib, and he now faces up to four weeks of rehabilitation.
"Dale dived while fielding a ball on day one of the second Test against India in Durban and complained of slight pain of his right anterior chest region," team manager Dr Mohammed Moosajee said in a CSA statement.
"He continued playing and bowling with mild discomfort for the rest of the Test. When the discomfort persisted after the match, a scan was performed which detected a small undisplaced fracture to his right eighth rib.
"He will follow a strict rest and rehabilitation programme for the next three to four weeks and we are confident he will be fit for the tour against Australia."
Steyn is not expected to play any part in South Africa's domestic Twenty20 competition, robbing the Cape Cobras of their front-line bowler.
Following their humiliating 5-0 thrashing of England in the Ashes, Australia will play three Tests and three Twenty20 internationals in South Africa, with the opening Test starting at Centurion on February 12.
