Leinster are set to be without several of their front-line internationals for Friday's Pro12 game with Glasgow Warriors which means they will be drafted straight back into side for next week's Champions Cup quarter-final against Bath.
Normally, teams have two Pro12 games to prepare for a European quarter-final but with the structural changes in this year's competition, the preparation time has been reduced for what will be a season-defining game for Leinster.
Forwards coach Leo Cullen (above) is anticipating that the players who started on the bench in Ireland's win over Scotland on Saturday will be available for selection while the starting players are likely to miss out.
"Some guys won't play this week, with a view to Bath the following weekend," he admitted.
"We have a lot of fit bodies that we didn't have earlier in the year. We'll just assess over today and tomorrow what bodies are in best shape to take us into Glasgow on Friday.
"We don't want to be flogging guys at this stage of the season because it is important that they get enough detail in their game and upskill in terms of what we do call-wise.
"It's unusual in the sense that, usually, we'd have two Pro12 games in the run-up to Europe where guys coming off the Six Nations can take a breath. It's a very short breath this year," Cullen added.
Cian Healy and Saturday's man of the match Sean O'Brien are both expected to be rested but Cullen is relishing their return for next weekend's quarter-final.
"We haven't seen them yet really, since very, very early in the season.
"They are two world-class players. It's great to have them, coming to this end of the season, where they are just starting to pick up form - they have looked better every week.
"To have those guys back is fantastic. Hopefully, the two of them stay injury-free for the run-in."
