(All tomorrow 2.30 unless stated)
LANSDOWNE v DOLPHIN
The Aviva Stadium, 2.0
Coach Mike Ruddock will have to deal with the loss of Connacht wing Matt Healy to injury as fly-half Craig Ronaldson returns to probably fill the number ten jersey.
ST MARY'S COLLEGE v CLONTARF
The champions are not making a hard fist of their defence of the title. They are not yet guaranteed safety against a fellow Leinster club still in the hunt for the semi-finals.
The Clontarf squad is intact. Leinster second row Mark Flanagan and centre Killian Lett will both come into contention for the first time this season.
YOUNG MUNSTER v OLD BELVEDERE
Tom Clifford Park
Props Declan Lavery (groin) and Pat O'Regan (groin) will be back to bolster the front row in what should be one for the forwards.
BRUFF v BLACKROCK COLLEGE
There is an almighty relegation scrap on, populated by these two clubs and the northern pair of Dungannon and Ballymena just below them. A win here would do wonders for 'Rock.
BUCANNEERS v UCD
Leinster Academy scrum-half Luke McGrath and wings Sam Coghlan-Murray and Andy Boyle will be back on board. Hooker David Doyle could also return from long-term injury.
DUBLIN UNIV v BELFAST HARLEQUINS
Leinster 'A' fly-half Cathal Marsh will step in for regular David Joyce. Openside Brian du Toit is away in South Africa. Will Scott could come into the back row. Prop Iain Hirst is back in the side.
