Uncertainty for Leinsters Johnny Sexton ahead of Champions Cup

Leinster say it remains uncertain if Johnny Sexton will be available for this Sundays Champions cup encounter with Montpellier in France.

The Ireland out-half missed Saturdays win over Castres due to a tight hamstring.

Rhys Ruddock is ruled out after tearing his calf last Saturday while Tadhg Furlong is unlikely to be available due to a hamstring injury.

In better news, Sean O'Brien is available having played for the A side last weekend.

Mike McCarthy is also available while Dave Kearney will be assessed as he recovers from an ankle injury.
