Munster are "playing a waiting game" on the fitness of skipper Paul O'Connell's fitness ahead of next month's Heineken Cup semi-final tie against Biarritz Olympique in San Sebastian..
The British & Irish Lions captain was a late withdrawal from the Munster side which beat Northampton Saints 33-19 in last weekend's quarter-finals with a groin injury.
O'Connell will also miss his side's Magners League clash against Connacht and is a major doubt for the trip to Spain for a re-run on the 2006 Heineken Cup final..
Munster team manager Shaun Payne said: "It is an injury that needs rest and we'll be taking that into account over the next few weeks leading up to the semi-final.
"It's not a broken arm or something where there is a defined recovery period. At the minute we're just playing a waiting game."
There was better news for wings Ian Dowling and Doug Howlett, who both underwent scans in the wake of the triumph over Northampton. Two-try hero Howlett suffered a hamstring strain, while Dolwing suffered a knee injury.
But both will be fit to face the French giants as Munster aim to reach the Heineken Cup final for the fifth time.
The directors of ERC voted unanimously at a Board meeting to postpone all decisions including the release of further instalments of ERC's distributable central revenues to the six shareholder countries until 19 February next when the Board will meet again to reconsider the issue.
