The decision was taken by both the England Cricket Board as well as the home board, Cricket South Africa.

In the interests of the safety and well-being of both teams, match officials and all involved in the match, the Acting CEO of  CSA, Kugandrie Govender as well as the CEO of the ECB, Tom Harrison, have agreed to postpone the first fixture to Sunday," the statement added.
