• Steyn suffers fracture in right shoulder
• Same shoulder as the one broken against England

Steyn broke the same shoulder nearly a year ago, forcing him out of tests against England.

The loss of the pace spearhead is a hammer blow for the tourists, who play two more tests against Australia in Hobart Adelaide.

The remaining bowlers rallied brilliantly in Steyn's absence, dismissing Australia for 244 on Friday before the Proteas batsmen pushed to 104-2 at stumps and a lead of 102 runs.

Steyn's absence may be felt more keenly if South Africa bowl again in Perth, with Vernon Philander and 21-year-old Kagiso Rabada to shoulder the pace burden alone.

Morne Morkel, who missed the New Zealand tests with a back injury, was rested for Perth and is likely to slot in for the remaining tests. Kyle Abbott is the other back-up seamer in the squad.
