(All Tomorrow 2.30, unless stated)
Old Belvedere v Lansdowne
Anglesea Road, Tonight 7.30
The Black & Whites, in second, have been consistent in their pursuit of Clontarf at the top and should have enough in the locker for this one.
Coach Mike Ruddock will be with the Ireland U20s tonight, leaving his assistant Emmet Farrell to mind the house, possibly with an unchanged combination.
St Mary's College v UCD
Templeville Road, Tonight 7.30.
The home club will look to get the drop on UCD by shoring up the second worst defence in the Division.
College will have James Tracy available for the front row, along with hooker Risteárd Byrne and lock Gavin Thornbury. Scrum-half Luke McGrath has been taken away by Leinster.
Clontarf v Cork Constitution Castle Avenue
Leaders 'Tarf will have to make do without some of their Leinster fringe players, like Tadhg Furlong, the line up being similar to last week.
Terenure College v Blackrock College, Lakeland's Park
Coach James Blaney has a doubt over Ryan Roopnarinesingh in the centre. It is just as well Graham Coffey is back in contention there for the leaders.
Coach Ben Manion will need his half-backs David Godfrey and Adam Griggs to control matters on what is likely to be a heavy pitch.
Dublin University v Dungannon Sydney Parade
Trinity were one kick away from victory last week and director of rugby Tony Smeeth is likely to trust the same players again.
NUIM Barnhall v Bective Rangers, Parsontown
Dennis Bowes brings in prop Dan Jennings and second row John Campbell as the two personnel changes in his pack of forwards.
New coach Barry Lynn scrambled a three penalties-to-one win over Old Crescent last week before what should be a more searching test at fourth-placed Barnhall.
OLd Crescent v Naas, Rosbrien
Player/coach Niall Carson goes with the same side again this week.
Old Wesley v Rainey Old Boys, Donnybrook
Coach Morgan Lennon makes a change at tight-head, with James Burton coming in for Dave Henshaw. Ian Cassidy moves to 10 from nine.
Seapoint v Galwegians Kilbogget Park
The Killiney club will have to be on their toes to prevent a third straight defeat against the League leaders.
Boyne v Nenagh Ormond, Shamrock Lodge
Coach Mike Walls' men will have to bring their A-Game against the League leaders, his young number eight Karl Keogh showing impressive form of late.
Greystones v Armagh, Dr Hickey Park
This is a tasty prospect as 'Stones, in second, host Armagh, in third, with both clubs looking for their eighth win from 10 rounds.
Instonians v DLSP, Shaw's Bridge
Salmo' coaches Phil de Barra and Victor Ball have doubts about centre Adam Philpott and their number eight Paul Tolofua.
Navan v Ards, Balreask Old
David Clarke will make his first home start at hooker beside impressive 19-year-old Australian prop Jacob Ginoli.
Richmond v Tullamore, Richmond Park
Tullamore will scheme to pick up points in Limerick. They will travel with the confidence from three wins and one draw from their last four.
Skerries v Midleton, Holmpatrick
The North Dublin club came within one score of handing Nenagh their first defeat of the season. That performance will be their benchmark on the run-in.
Thomond v Suttonians, Fitzgerald Park
Coach Noel Hehir sticks to the same side with the plan to make up for last week's defeat.
