Ireland centres Brian O'Driscoll and Gordon D'Arcy have flown to Spala in Poland to continue their rehabilitation from hamstring injuries.
Skipper ODriscoll and DArcy were ruled out of Irelands 40-13 RBS 6 Nations Championship win over Scotland at Murrayfield on Saturday.
The injured pair have travelled with the teams athletic trainer Brian Green to the specialist cryotherapy centre in Spala, which was previously used by the Irish squad for pre-season training.
They will return to Ireland later in the week and any update regarding their injuries will not be known until Sunday at the earliest, when both players' injuries will be assessed.
Ireland coach Eddie OSullivan will be hoping they are fit in time for Irelands next RBS 6 Nations assignment against England in Dublin on February 27.
