Leinster will go into the battle with Brive next weekend cold after their last two fixtures have been frozen off.
The Heineken Cup holders were due to warm up with a tough test against current Magners League leaders Glasgow Warriors, but the big freeze has seen that fixture shelved.
That cancellation comes hot on the heels of their scrapped match with Connacht last weekend and means Micheal Cheika's side won't have played a competitive match since their Boxing Day win over Ulster.
Coach Cheika commented: "We would have liked to have played this game before the Brive game next weekend, without a doubt, but we'll take the cards we're dealt and we'll get the best preparation possible underway ahead of that match."
Chief Executive Mick Dawson explained the reasons for the cancellation: "Unfortunately the pitch is unplayable despite a huge amount of effort made by the RDS ground-staff over the last week to get the game played. The weather just caught us out in the end because we were confident that it could go ahead up until yesterday evening
"Following Garda and Health & Safety advice, we had to consider supporters travelling to the game from the far reaches of Leinster and beyond as well as the safety of the players as the roads and pathways around the ground are also treacherous."
