Fergus McFadden has been ruled out of the game but has made great strides over the last week in terms of his recovery from a knee injury suffered in the game away to Toulon in the Heineken Cup.
Otherwise Luke Fitzgerald and Eoin Reddan trained but a decision on their inclusion or otherwise will not be made until later in the week when they will be assessed further.
Tadhg Furlong suffered no reaction to the ankle injury after his return to competitive action in Saturday's Leinster A away win in the Semi-Final of the B&I Cup.
Otherwise Sean O'Brien is continuing his modified training programme and while he isn't too far away from taking part in team training, no date has been set for his return.
The squad to face Ulster will be announced at midday on Thursday.
