Joey Carbery is believed to be strongly considering a short-term deal to move to Ulster just for next season.
The Leinster playmaker is contemplating leaving his home province on order to secure his position as one of the Ireland out-halves for the 2019 Rugby World Cup.
Coach Joe Schmidt has made his opinion known that Carbery needs significant game time at out-half next season.
However, Schmidt does not have the power to insist coaches Leo Cullen and Stuart Lancaster hand him the number 10 shirt at Leinster.
It is understood Schmidt and Carbery met for a discussion in a Dublin 6 café on Sunday.
Leinster are concerned at the price they have to pay for bringing through Ireland international and whether it could hinder their ability to compete on two fronts next season, especially in the Champions Cup.
