Jacques Kallis took two key wickets then limped off with an injured right hamstring in another injury setback for South Africa on the opening day of the second cricket test against Australia.
South Africa's attack was already missing paceman Vernon Philander, who woke with a bad back and withdrew from the XI, and will have difficulty covering for Kallis, who was playing in his 157th test.
A team spokeswoman said the 37-year-old Kallis was set to have an MRI scan later Thursday and wasn't expected to return to the field on day one.
The Australians gained the early momentum and were coasting at 43 without loss before Kallis struck in his first over to dismiss Ed Cowan (10).
After Morne Morkel removed Rob Quiney (0) and Kallis bowled Ricky Ponting (4) to have Australia reeling at 55-3. But momentum swung back in Australia's favor when Kallis left the field during in the 17th over.
He was only three balls into his fourth over and had figures of 2-19 when he pulled out of his delivery stride, handed the ball over and walked off. Australia was 77-3 at the time.
Rory Kleinveldt finished off the 17th over and had to take on extra responsibility on day one. He was initially left out of the starting lineup after failing to take a wicket in his test debut last week, but was reinstated when Philander withdrew in the hour before the Adelaide test.
