Leinster have rated Robbie Henshaw as doubtful to be fit for Saturday's Guinness Pro 14 final against Scarlets.
The Westmeath man missed the win over Munster with a knee injury, picked up in the Champions Cup final win over Racing 92.
The province is more hopeful about the prospects of Johnny Sexton (calf and groin), Dan Leavy (hamstring) and Isa Nacewa (calf).
Lions and Ireland fly-half Sexton is due to resume training this week. But the others aren't expected to train until a further assessment of their fitness, later in the week.
Scrum coach John Fogarty said it isn't overly important the players train a lot in the next few days after the events of the month so far: "We have to be mindful of the highs and emotional energies that went into the last two weeks, as well as the physical stuff.
"In that sense we'll have to reduce a little bit of the onfield work. But we're prepping for a team we have played four times this season. If we paid lip service to them, we'd come undone. They are a dangerous side. For us it's time to focus massively on the threats they have and the opportunities for us.
"The work that has to be done today and tomorrow in being clear in our heads so we can deal with Scarlets is very important. If anything we'll ramping up on that side of the game and tapering down so of the physical stuff.
"These are lads that came over last year and beat us in a semi-final and now they have beaten Glasgow in semi-final. They went on to beat Munster in a final last year.
"We are under no illusions into how dangerous they are. We need to prep for them for a final in it being a final because cup rugby is just a different game.
"We have to manage them early in the game. A lot of energy goes into that this time of the week."
Fogarty added that everyone is rooting for Nacawa to be fit to complete a dream goodbye to his playing career.
"Isa, at his stage physically, it's always difficult for him. He is going to do all he can to get on the field. We hope he can. We're all pulling for him because he is so important to everything we are about.
"We want to make sure he goes on a good note so hopefully he gets on the pitch. We'll see.
"Isa's values and the type of person he is............he has given so much. He has been a servant to Leinster and the players around him. We need to make sure we're serving him at the weekend whetehr he plays or not."
