Jamie Heaslip's participation in the last two rounds of the European Champions Cup is not yet assured.
The number 8 is recovering from a shoulder injury suffered against Ulster 2 weeks ago.
Leinster assistant coach Leo Cullen was asked if Heaslip's recovery is going perfectly
Cullen refused to rule out Cian Healy who has been back in training after that torn hamstring.
Healy could feature in the last two matches against Castres and/or Wasps while Shane Jennings is good to go.
With the Six Nations looming, Cullen was asked if it would be folly to throw Healy back in for 2 such massive games
