The first ODI between South Africa and England has been cancelled due to two positive covid test results from members of their hotel staff.
The news meant that England's squad and support staff went through a further unexpected round of testing late on Saturday night and are awaiting those results before they even contemplate playing again.
But even if England return a full set of negative results the ease with which their own bubble has been breached has confirmed their huge concerns over its security.
And with the tour already on a knife edge, this latest set of positive results could be enough to bring the tour to a premature end without any games played.
