Rhys Priestland will have a weekend off for the Scarlets
Munster's Magners League clash with the Scarlets scheduled for Sunday at Musgrave Park has been postponed.
The pitch had been covered by a warm air blanket since Friday morning at which stage officials were confident that the game would go ahead.
However overnight temperatures dropped to minus nine centigrade and with a further deterioration forecast on Saturday, the game was called off.
There is no news yet on when the game will be played.
Munster chief executive Garrett Fitzgerald said that the Irish province had been optimistic that the game would go ahead.
"While our inspection this morning showed part of the pitch unplayable, the continuing use of the warm air blanket' would, in our opinion have left the pitch playable by 5pm tomorrow if conditions remained as they are now," said the Munster chief.
"However, given the forecast of lower temperatures and snow overnight, we felt it would be unfair to those travelling or planning to travel to leave a final decision until the morning."
Scarlets officials are likely to be pleased that an early decision was taken so that the possibility of a fruitless journey to Cork has been avoided.
