South Africa have added Stephen Cook to their squad for the fourth and final Test against England in Centurion.
The Highveld Lions opener, whose father Jimmy played three Tests for South Africa, currently sits atop of the Sunfoil Series batting averages with 415 runs at an average of 83.
Cook made an unbeaten half-century against England for South Africa A in a warm-up match before the series and looks set to replace the out-of-form Stiaan van Zyl.
If Cook is selected for the final Test on Friday, he will be part of the first ever father and son combination to represent the Proteas in a Test match.
CSA Selection Convener Linda Zondi said: “Stephen has been in excellent form this season and gives us another option at the top of the order,”
Dale Steyn retains his place in a 17-strong squad for Friday’s match at Supersport Park, but is thought to be struggling with the shoulder injury that has kept him out of the past two Tests.
Quinton de Kock is also set to return as wicketkeeper.
He was ruled out of the third Test after injuring his knee while walking his dogs, but his replacement Dane Vilas has not been included this time.
