Munster's Pro14 fixture against Benetton on Saturday has been postponed after the Italian club confirmed three further players have tested positive for Covid-19.
Benetton were unable to travel to Galway for last month’s game with Connacht due to a "small number of isolated positive cases".
They had hoped to return to action against Munster at Stadio Comunale di Monigo but that was shelved after the latest round of testing revealed three more positive cases.
Four other players have been identified as close contacts and are also isolating.
A Pro14 statement read: "Having considered all of the available evidence, the Pro14 Rugby Medical Advisory Group has deemed that this fixture cannot go ahead as scheduled.
"Pro14 Rugby will examine potential dates in early 2021 to reschedule the game."
