Robbie Henshaw is likely to miss the opening of the Six Nations championship as Leinster indicate he will sit out the next eight weeks with a hamstring injury.
The outside centre hasn't played since pulling his hamstring in the warm-up before Ireland's victory over Argentina in the November series.
After assessing his injury, Leinster today indicated he will sit out the next eight weeks, meaning he will likely not be fit in time for the opening Six Nations game at home to England on 2 February.
Henshaw has endured a heavily injury-interrupted season.
He previously missed the three Six Nations victories over Wales, Scotland and England after damaging his shoulder in the act of scoring a try against Italy.
He did, however, feature in all three Tests in Ireland's 2-1 series victory over Australia in the summer.
Elsewhere on the injury front, Johnny Sexton will be assessed after being withdrawn with calf problems during Leinster's narrow win over Bath in the Recreation Ground on Saturday.
Winger Barry Daly is returning to fitness after his knee injury though will remain unavailable for selection for the visit of Todd Blackadder's side.
