Leinster have received positive news on Josh van der Flier, Isa Nacewa and Seán Cronin ahead of their PRO12 match against Cardiff Blues.
The trio could return on Saturday while Leinster scrum coach John Fogarty added that all 16 Ireland players are being assessed case by case.
Van der Flier (AC), Nacewa (knee) and Cronin (hamstring) all took part in training last week and were expected to step up their recovery again on Monday ahead of further assessment later in the week.
"There was also positive updates on Dave Kearney (toe) and Dominic Ryan (knee) who have both stepped up their recovery but would not be available for selection this week," added a Leinster statement.
"Rob Kearney (knee) and Jamie Heaslip (lower back) were also ruled out of selection this weekend due to injury.
"Kearney picked up a knee injury in Ireland training last Tuesday and will see a specialist tomorrow, while Jamie was withdrawn from the Ireland against England game very late in the warm up and has a lower back injury.
"Long term absentee Jordi Murphy continues to rehab from his ACL injury."
