Title tilt is still Young for the boys of Belvo
(2.30, Saturday unless stated)
Old Belvedere v Young Munster, Anglesea Rd
Phil Werahiko's men refuse to accept the natural order of life at this level. Andrew Dunne will continue at scrum-half because Simon Keogh is away for the leaders.
St Mary's College v Dolphin, Templeville Rd
Coach Ciaran Potts will want what is likely to be the same side to copper-fasten third place with Dolphin making up one of three Munster clubs on St Mary's heels.
Garryowen v Blackrock College, Dooradoyle
This is a must-win scenario for the bottom two clubs. 'Rock will be without Leinster pair Andrew Conway and Brendan Macken.
Clontarf v Dungannon, Castle Avenue
An unchanged 'Tarf continue to hold sway at the top despite securing just a losing bonus-point at Buccaneers. The lead is cut to two points.
Galwegians v Lansdowne, Crowley Park
Willie Clancy's troops were sickened by suffering a home defeat by UL-Bohs. They will not find 'Wegians an easy place to recover confidence.
UCD v Ballynahinch, Belfield
This is the big one. Two 100pc clubs. Second versus first. College can overtake 'Hinch with victory. Otherwise, the Ulster club will take on the appearance of champions-elect.
Dublin University v Clonakilty, College Pk
Trinity made a good fist of their visit to Ballynahinch last Saturday. They should have enough to handle Clon' with Dominic Gallagher returning at openside.
Belfast Harlequins v Bective Rangers, Deramore Pk
Rangers can move back into third by leapfrogging 'Quins in a difficult assignment in Belfast. Prop Alitase Ali will be back to face his former club.
Midleton v Terenure College, Towns Pk
Director of Rugby Ian Morgan will not want to absorb a hat-trick of losses. Lock Brian Moroney is out and flanker John Dever, hooker Robbie Smyth and full-back Adam O'Loughlin are struggling.
Naas v Suttonians, Forenaughts
Coach Niall Carson will want Naas to show better execution in attack. They haven't scored a try in their last two matches. The return of Steve McGrath to stand-off could help. Suttonians will not want to rest on their laurels. Director of Rugby Robert Forbes brings Paul Proctor in at number eight.
Wanderers v Connemara, The Aviva Stadium
The Merrion club is staring straight into the face of their seventh straight defeat as they tumble down the table. Lock Paul Huntly could be back from injury.
Highfield v Seapoint, Woodleigh Park
There was no shame for Seapoint in coming up slightly short of leaders Instonians last Saturday. The same personnel must get back to winning right away.
Instonians v Navan, Shaw's Bridge
Navan will find no solace at the unbeaten leaders. Alan Hickey moves out to fly-half with Ciaran Joyce in at nine.
Nenagh Ormond v Greystones, New Ormond Park
'Stones will look to their high-powered attack to deliver the goods with what is likely to be the same side.
Sunday's Well v NUIM Barnhall, Musgrave Park
Denis Bowes' Barnhall are tucked away nicely in mid-Division. Last week's postponement means he will go with the same side selected then.
