Johnny Sexton won't feature in Ireland's Six Nations clash with France in Paris on Saturday.
The captain has been ruled out with a hamstring strain he sustained in training yesterday.
Munster's Joey Carbery comes into the side in the only change to the team from last weekend's win over Wales.
It's set to be Carbery's first Six Nations start.

Sexton's injury is not believed to be overly serious, with Farrell telling media that he is likely to be back in ten days.
That means the Leinster man is likely to be back in contention for Ireland's clash with Italy in a fortnight's time.
There is no game the weekend after next.
Meanwhile, James Ryan has been handed the captain's armband in Sexton's absence.
Mack Hansen retains his place on the wing after an impressive debut last week.
Connacht out-half Jack Carty is among the replacements, as is Ulster's Iain Henderson and Leinster's Robbie Henshaw.
France have made two changes to their side, following their 37-10 win over Italy.
Yoram Moefana comes in for the injured Jonathan Danty at inside-centre, while Francois Cros starts in the back row.
Dylan Cretin drops to the bench.
