Port Elizabeth - South Africa called up wicketkeeper-batsman Quinton de Kock as cover for unwell opener Alviro Petersen on the eve of Thursday's second test against Australia at St George's Park.
Petersen has a viral infection and a decision on his fitness will be made on the morning of the match (today).
The 21-year-old De Kock, who was handed a central contract by Cricket South Africa on Tuesday, has not played test cricket but is a rising talent in the one-day international side.
Opening the batting, he scored centuries in three consecutive innings against India in December.
If left-handed batsman De Kock is selected he will likely take over as wicketkeeper from AB de Villiers.
Australia lead the three-test series 1-0. Reuters
