Vernon Philander withdrew from the second crickettest against Australia after waking up with soreness in his back Thursday, asignificant setback for South Africa.
Team manager Mohammed Moosajee said the 27-year-old paceman"woke up complaining about lower back stiffness, he progressively gotworse and didn't respond to the treatment from our physiotherapist."
Philander was due to have MRI scans, Mossajee said, "togive us a clearer indication of the symptom."
Rory Kleinveldt, who was initially dropped after the drawnfirst test in Brisbane last week, was reinstated to the starting XI forAdelaide.
Philander needed only seven tests to reach the 50-wicketmilestone, the second-fastest in test history. He has 63 wickets in his first11 tests, but struggled on a flat wicket at Brisbane.
