Back three virtuoso Isa Nacewa could be available from his hand injury and lock Tom Denton is also showing promising signs of returning to the fray for Friday.
There is also positive news about second row Quinn Roux, who has impressed the coaching staff on the training paddock without being able to put in the game time to deliver on his undoubted potential.
The South African has not been able to play since receiving a chest injury against Connacht in September that has been difficult to shake.
Sadly, wing Luke Fitzgerald, centre Eoin O'Malley, who would come into contention for what would be his 50th cap, and flanker Dominic Ryan are less likely to be involved.
It is probable that they will have to look at the following week against Zebre as their most likely return-to-play targets.
Meanwhile, the ticket sales for Leinster's crucial Heineken Cup pool match against Clermont-Auvergne at The Aviva Stadium on December 15th have passed the 33,000 mark.
