(all TOMORROW 2.30 unless stated)
Clontarf v BallynahiNch, Castle Avenue (2.0)
'Tarf have been hindered by the success of bringing through so many Leinster men, like Tadhg Furlong and Bryan Byrne, as they look to hang onto the leaders' coat-tails.
Terenure College v Old Belvedere, Lakelands Park (2.0)
It is not how you fail but how you react to failing that counts. Coach James Blaney will drive the importance of recovery from 'Nure's first defeat.
OB stand in the firing line in one of those make-or-break situations as they look to climb up from fifth with Danny Riordan showing the way from full-back.
Dolphin v St Mary's College, Independent Park
Second last St Mary's are staring right into the abyss in what is a true blue eight-pointer as the bottom two face-off in a basement battle.
Lansdowne v Young Munster, Aviva Stadium, Sunday
Mike Ruddock's men just about ended Terenure's perfect start to be second and they should have centre Mark Roche back from injury.
UCD v Cork Constitution, Belfield Bowl, Sunday
College could overtake Cork Con if they can pull this off with Leinster looking to Liam Bourke and Bobby Holland at half-back.
Dublin University v Corinthians, College Park (2.0)
Trinity have won three and drawn one of their last four to rise to fifth on the ladder and tight-head Andy Keating is back.
