Munster are still unsure if Peter O'Mahony will be available for this weekend's Heineken Cup clash with Edinburgh.

The Munster captain suffered a knock to the head during last Saturday's win over Leinster and the province are waiting to see if he will be cleared for the trip to Murrayfield this Saturday.

Head coach Rob Penney is set to make a decision on the flanker's fitness on Thursday.

Meanwhile, Connacht could be without Eoin Griffin for their opening two pool games.

The province have confirmed that the centre is definitely out of this Friday's opening match against Saracens at the Sportsground after suffering a ligament tear in his foot that could keep him out of action for up to five weeks.

Ronan Loughney and Nathan White are also doubtful for Friday's game through concussion and a calf injury respectively.
