(2.30, Saturday unless stated)
Old Belvedere v Blackrock College, Anglesea Road
Phil Werahiko's men have lost the lead, but remain a powerful presence in second.
Mark Cooney (groin) and Dean Moore (groin) are out, but flanker Richie Leyden returns from a broken hand.
'Rock are looking anything but rock solid. There is consolation in the fact they are just three points away from fourth-placed Young Munster.
Shannon v St Mary's College, Coonagh
Gavin Dunne's drop goal kept St Mary's out of Young Munster's reach. Coach Ciaran Potts will look to move onto the 66pc win return to maintain a push for the play-offs.
Lansdowne v UL-Bohemian, The Aviva Stadium
Willie Clancy's Lansdowne have been consistently inconsistent in losing every second match over the last six rounds. Former Ireland flanker Aidan McCullen should make his first start of the season.
Buccaneers v Clontarf, Dubarry Park
Leaders 'Tarf will look for their fifth win on the spin in a first-versus-second clash of serious contenders.
Mick Kearney has been taken by the Ireland U20s. Conor O'Keeffe will start at lock.
Bective Rangers v UCD, Donnybrook, 4.30
Kevin Lewis's Rangers, in third, can move into second on the ladder if they can win without conceding a bonus-point here.

The Donnybrook club were buoyed by their bonus-point execution of Thomond. John Carroll moves into lock and Richie Murphy comes in at flanker.
Ballynahinch v Dublin University, Ballymacarn Park
This is like going into the fox's den with rabbit written across your forehead. 'Hinch look unstoppable. David Joyce might have to step into the breach at centre for Conor Colclough.
Thomond v DLSP, Fitzgerald Park
An unchanged Salmo' can confirm their survival by clipping the wings of the second-from-bottom Limerick club.
NUIM Barnhall v Suttonians,
Mid-table Barnhall have reached that point in the season where they can drift or drive. Ben Harrison, Jim Nolan and Conor McDermott all come into the front five.
Suttonians experienced lock Aidan Kearney will look to build on his first AIL game back last week.
Greystones v Ards, Dr Hickey Park

The Killiney club is on the brink of something special, standing two points behind their visitors with the live possibility of going top.
City of Derry v Wanderers, Judge's Road
Wanderers have lost their last five to leave them close enough to the edge of the cliff. Shane Hogan, Karl Duffy and Sean Byrne come into the front five.
