Leinster will have to plan without their Grand Slam superstar Jordan Larmour for next weekend's Champions Cup quarter-final against Saracens.
armour had been expected to play a key role against the double European champions, but a leg injury has ruled him out.
The 20-year-old, who came off the bench at Twickenham last weekend, is expected to be sidelined for three weeks.
Should Leinster beat Saracens, they would be looking at a potential semi-final clash on the weekend of April 21, with Larmour hoping to return against Benetton in the Guinness PRO14 the previous week.
The versatile back underwent a scan on his leg earlier this week and while it showed minor damage, it is not expected to keep him out for a prolonged spell.
Elsewhere, newly-appointed technical consultant with London Irish Declan Kidney has said that he would be open to forming a new partnership with the IRFU.
"My understanding was that things were very close before," the former Ireland boss said.
"When it was set up there was a massive Irish influence around the club and since then it has become more (diverse).
"Ideally, if we can be of any assistance at all we would only be too delighted - but the IRFU have enough of a task in looking after the four provinces without having to look after us in any way.
"If we can help out, Les (Kiss) and myself will be only too happy to do that."
