Munster's upcoming Heineken Champions Cup games have been thrown into major doubt.
A member of their traveling party in South Africa has returned a positive Covid-19 test.
It is not yet known if it is the Omicron variant.
The province says they will remain in Cape Town, where their two United Rugby Championship games that were planned for this weekend and next were postponed on Friday, until further notice.
Johann van Graan's side are due to take on Wasps in their opening European game of the season on Sunday 12 December and Castres six days later.

A brief statement from Munster on Sunday afternoon read;
"This morning Munster Rugby were making plans to join their fellow URC sides in departing Cape Town for Dublin by charter.
"After arriving at their hotel in Cape Town late last night the squad underwent a round of PCR testing ahead of today’s possible departure.
"The returning results have identified one positive case.
"In taking all precautions and prioritising the health and wellbeing of everyone Munster Rugby will not travel today and will return to their hotel for an isolation period as a matter of priority.
"The province will await further guidance from the health authorities."
