New Ireland coach Andy Farrell praised the true grit shown by his side in beating Scotland to open their Six Nations campaign, but has been left counting the cost as injuries mount.
The hosts won 19-12 in Dublin with captain Johnny Sexton bagging all his side's points but they were pushed all the way by a better than advertised Scots.
"Our performance was summed up in the last five minutes," said Farrell. "We asked the lads to stand for something this week and you could easily see the true Irish grit.
"There were guys out there not used to playing for so long but due to injuries were still tracking back in the final five minutes. The pack was magnificent."
The chief injury concern will be Garry Ringrose, who is seemingly set for a spell on the sidelines with a suspected broken finger.
The in-form outside centre was removed at half-time and, with an IRFU update due today before the team to face Wales is revealed tomorrow, Robbie Henshaw is in line for a promotion.
Elsewhere, both No 8 Caelan Doris and reserve loosehead Dave Kilcoyne will go through the return to play protocols having been removed after heavy head knocks, while Tadhg Furlong suffered calf tightness.
