Leinster say that Jamie Heaslip remains 50-50 to feature in this Saturday's European Champions Cup clash with Castres at the RDS.

The Leinster captain suffered a shoulder injury during his side's recent Pro 12 win over Ulster and forwards coach Leo Cullen has admitted that he is still working his way back to full fitness.

Cullen has also confirmed that Cian Healy and Sean O'Brien are to continue their return to fitness, while Shane Jennings is available again this week.
