Leinster are assessing a foot injury Jordan Larmour sustained in last Saturday's Heineken Champions Cup defeat of Benetton Treviso.
The province secured top-seed status and a home Heineken Champions Cup quarter-final against Saracens when they made it a record-breaking 16 wins in a row in all competitions this season with an 18-0 victory in Italy.
However they did not come out of that clash unscathed, with 22-year-old Larmour suffering what Leinster have described as "a low grade foot injury".
Larmour was included in Andy Farrell's first Ireland panel last Wednesday ahead of the Six Nations opener against Scotland on 1 February at the Aviva Stadium.
He's one of 19 Leinster players included in Farrell's squad, which will head for a training camp in Portugal ahead of the Scottish clash.
