South Africa suffered a third injury concern on their England tour after left-arm spinner Keshav Maharaj tweaked his groin in the warm-up of the first T20I in Cardiff.
After the match, which South Africa won on by 14 runs on DLS , captain Aiden Markam confirmed Maharaj was due to play the game but was forced out with the injury and replaced by Corbin Bosch. Maharaj had been recalled to the T20I squad after being left out in Australia and Zimbabwe.
Earlier in the day, Lungi Ngidi was ruled out of the series with a right hamstring strain. Ngidi will return home on Thursday and faces a race against time to be fit for South Africa's next assignment - the start of their World Test Championship (WTC) title defence in Pakistan which begins on October 12.
