Stephen Archer will miss Munster's Heineken Cup semi-final clash with Clermont this weekend after sustaining a wrist injury in the RaboDirect PRO12 game against Dragons last Friday.

He is looking at over four weeks to recover from the injury after dislocating a bone in his left wrist.

Munster trained today in UL ahead of their semi-final assignment at Stade de la Mosson, Montpellier.

The news on the injury front is that doubts remain over Peter O'Mahony (hip), Donncha O'Callaghan (knee), Keith Earls (hamstring), James Downey (hand) and Doug Howlett (shoulder) while Mike Sherry didn't train because of tonsilitis.
