Uncapped opener Stephen Cook has been added to South Africa's squad for the fourth Test against England at Centurion, starting on Friday live on Sky Sports..
Cook, 33, scored an unbeaten 53 playing for South Africa A in a warm-up match with England, which the tourists won by an innings.
The Highveld Lions player, who has scored two centuries in his last three matches, is the son of former South Africa batsman Jimmy Cook, a familiar face in England after a successful spell in county cricket with Somerset.
He appears likely to replace Stiaan van Zyl at the top of the South Africa batting order, although Van Zyl has been retained in a 17-strong squad which also includes Dale Steyn.
Steyn is still struggling with a shoulder injury and might not be risked in the series finale with England already having an unassailable 2-0 lead.
Quinton de Kock will undergo a final fitness test on Wednesday after missing the third Test in Johannesburg with a knee injury he sustained while walking his dog - Dane Vilas, who replaced De Kock behind the stumps at Wanderers, has been left out.
