The second one-day international between South Africa and England, set for Monday, has been postponed.
It was a decision taken jointly by Cricket South Africa (CSA) and the England and Wales Cricket Board (ECB).
They are waiting for independent confirmation of “unconfirmed positive Covid-19 tests” for two unnamed members of the England tour party.
Limited-over games on Friday and Sunday were called off after positive tests by a South Africa player and hotel staff.
After Sunday’s first ODI was abandoned, England said two of their party had returned “unconfirmed positive tests”.
Once the unconfirmed tests have been reviewed, CSA and the ECB will then “discuss how best to proceed concerning the remaining two matches of this ODI series”.
