A complete guide to all the weekend's action:
Today
National Hurling League
Division Two B
Kerry v Westmeath, Tralee, 1pm - Important for both teams with play-off aspirations. Westmeath look better.
Connacht Under-21 FC
Galway v Leitrim, Pearse Stadium, 2.30pm - Leitrim have not won a match in this grade for nine years. This Galway side should prolong the visitors' wait.
Munster Under-21 FC
Waterford v Cork, Dungarvan, 3pm - Cork will be wary after Kerry's shock exit last week, but forewarned is forearmed.
Clare v Tipperary, Kilmallock, 3pm - Clare will really fancy their chances after defeating Kerry.
Ulster Under-21 FC
Monaghan v Cavan, Clones, 1pm - Cavan should negotiate this.
Tomorrow
National Hurling League
(3.30pm unless stated)
Division One A
Down v Cork, Ballygalget, 1pm - Straightforward for Cork in terms of the result and an opportunity to experiment. Anthony Nash gets a rare chance in goal and Pa Cronin gets the expected shot at full forward, as Gerald McCarthy reviews his options.
Wexford v Offaly, Wexford Park- Like Cork, John Meyler's side get to look at themselves in the absence of a long-established goalkeeper with Dermot Flynn coming in for Damien Fitzhenry. Diarmuid Lyng is back in the team, this time at centrefield. It looks strong enough to take the points against an side in the midst of an injury pile-up.
Clare v Waterford, Cusack Park, 1.30 - Waterford have started well with wins over the most likely play-off rivals. John Mullane and Tony Browne are back, but not named in the starting line-up, which is the same as defeated Cork. Clare are likely to welcome back Frank Lohan and Gerry O'Grady, but Diarmuid McMahon is unlikely to have recovered. Waterford got stung here in a qualifier two years ago, but the visitors still get the nod.
Division One B
Tipperary v Antrim, Templemore, 1pm - Excellent win for Tipp two weeks ago and, in tomorrow's match, Michael Keating takes the opportunity to inspect his reserves.
Brendan Cummins joins his illustrious peer group of David Fitzgerald, Donal Cusack and Damien Fitzhenry in the stands, as Gerry Kennedy gets a run in goal. Last year's under-21 James Woodlock is another under the microscope.
Antrim make a host of changes, despite not having played against Dublin a fortnight ago, but won't be pushovers.
Dublin v Galway, Parnell Park(Live TG4) - It's a big jump up for Dublin to play Galway live on television having had no chance to build on the opening-day draw against champions Kilkenny. They name the same side that turned up for the postponed Antrim match in Belfast.
This is a different challenge against the top side in the division. Ger Loughnane gives an outing to a new full forward line of Kevin Brady, Ger Farragher and Niall Healy. Galway to maintain momentum.
Division Two A
Meath v Derry, Páirc Tailteann- Suitably boosted by the acquisition of Eoin Brislane, Meath got on track last time out and should continue that way.
Armagh v Laois, Keady, 2.30pm - Fresh from the stunning loss to Wicklow, Laois's rehab starts here.
Carlow v Wicklow, Dr Cullen Park- A significant test of Wicklow's new status against a Carlow side touched off by Meath last week. Home side to win.
Division Two B
Mayo v London, Castlebar, 1pm - Mayo to build on the fine win over Kerry.
Division Three A
Monaghan v Donegal, Rooskey; Leitrim v Sligo, Ballinamore.
Division Three B
Tyrone v Roscommon, Omagh ; Cavan v Fermanagh, Kingspan Breffni Park .
Leinster Under-21 FC
Westmeath v Laois, Mullingar , 3pm- Laois will have benefited from last week's close encounter with Louth and can come away from this intact.
Offaly v Meath, Tullamore, 3pm - This Offaly team is very well regarded, but Meath have the edge and can join Laois in the provincial final.
