South Africa fast bowler Dale Steyn will not bowl again in the ongoing first Test against England in Durban due to a shoulder strain, and is a doubt for the second Test, starting at Newlands from 2 January.
Steyn, who is the world's premier paceman, injured his shoulder while bowling his fourth over of the second innings and left the field to have treatment.
The speedster later returned to the field but went off again after bowling only three balls, and was sent to hospital to have a scan done.
Although the scan showed no tear, Steyn woke up on the fourth morning in some discomfort and was withdrawn from the pre-day warm-up.
Proteas team manager Dr Mohammed Moosajee said: "The scans have shown there's no tear, no strain so we're treating it very much as stiffness.
"He's still in pain this morning and it's unlikely he'll bowl today. We'll monitor him throughout the Test and we'll have to make a call regarding his availability come Cape Town."
