Leinster have confirmed that Cian Healy is a doubt for this Saturday's Heineken Cup clash with Northampton.

After missing last Saturday's win over the English Premiership side, Healy went for scans on an ankle injury this morning and a decision on his availability will be made later in the week.

The province say that Sean O'Brien should be available for the return leg against the Saints after picking up a dead leg during last weekend's convincing win at Franklins' Gardens.

Meanwhile, Munster scrum-half Conor Murray is a doubt for next week's Heineken Cup return clash with Perpignan.

The Ireland and Lions star picked up a knee injury in yesterday's win over the French side at Thomond Park.
