Dale Steyn could yet bowl again for South Africa in the first Test with England, despite twice failing to complete an over on day three due to a shoulder injury.
The top-ranked bowler in Test cricket left the field two balls into the seventh over of England's second innings at Kingsmead on Monday due to a muscle spasm.
Steyn returned to the field to resume his spell, but again pulled up in pain and was unable to return to the attack for a third time.
Proteas team doctor and manager Mohammed Moosajee revealed that the paceman, who was sidelined for much of his side's recent Test series in India due to a groin injury, will be left to decide whether he bowls on day four.
England took charge on day three in Durban, closing on 172-3 to lead by 261 after bowling South Africa out for 214 - with Dean Elgar making an unbeaten 118.
Joe Root was 60 not out at stumps after being dropped by wicketkeeper AB de Villiers when he had just six runs to his name, while Nick Compton was twice reprieved on his way to 49.
