The Proteas suffered a serious setback when Anrich Nortje, a vital bowler for South Africa, was forced to miss the white-ball series against Pakistan because of a toe injury.
Dayyaan Galiem, an uncapped all-rounder, has been selected to take his spot.
With an outstanding T20 record of 46 wickets in 60 games, the 27-year-old was keen to establish himself on the global scene.
Nortje was hurt at a critical moment.
Since the ICC Men’s T20 World Cup final in June, when he took 15 wickets and was the team’s breakout performer, the pacer had not played for South Africa.
In an effort to control his workload, he recently chose not to sign a national contract, further taxing the Proteas’ bowling resources.
