Peter O'Mahony and Oli Jager have been ruled out of Munster's URC derby clash with Leinster at Croke Park on Saturday while Graham Rowntree is waiting of confirmation on the availability of Mike Haley, Tom Ahern and Alex Nankivell.

Both tighthead prop Jager and flanker O'Mahony were first-half withdrawals due to injury in last Saturday's 23-0 bonus-point win at home to Ospreys in Cork and respective neck and hamstring issues have made them unavailable for the round-four clash in Dublin.
