Andrew Porter is set to make his 100th appearance for Leinster against Munster at Thomond Park on St Stephens' day.
The Leinster prop has been named to start against their old rivals in the traditional post-Christmas interpro clash between the two sides.
Porter started in last week's European Champions Cup win over Gloucester and is one of ten players to retain their place in the starting line up for the Munster clash.
