According to a report in the Sunday Times today, Joe Schmidt and the IRFU are anxious that either one of Leinster's back-up out-halves: Athy's Joey Carbery and Ross Byrne - move to Ulster to replace the exiled Paddy Jackson.
According to the report iIRFU performance director David Nucifora visited the Leinster training centre to tell Leo Cullen that he needed to make a choice between the two.
With Jackson's contract revoked, Ulster are having a poor season anyway.
Joe Schmidt is said to be anxious that Carbery gets regular game-time at out-half, ahead of next year's World Cup.
The 23-year old Byrne has yet to be capped by Ireland .
The switch has been mooted several times before but Carbery has insisted in the past that he is happy at Leinster .
