A host of intriguing provincial club semi-finals are taking place this afternoon.

In the Leinster hurling championship, Kilcormac-Killoughey and Castletown Geoghegan lock horns at 12.45pm for a place in the final.

Westmeath's Castletown Geoghegan caused a big upset when knocking out Kilkenny’s Thomastown in the previous round.

Managed by former county football star Alan ‘Budda’ Mangan, the team is full of dual stars.

They are the underdogs again against Offaly’s Kilcormac-Killoughey, who defeated Carlow’s St Mullins by five points in their quarter-final, with the game the first of TG4's live offerings this afternoon.

With young talents like Charlie Mitchell, Adam Screeney and Colin Spain, Kilcormac-Killoughey are a serious force and are gunning for their first provincial title since 2012.

The other Leinster semi-final sees Dublin’s Na Fianna take on Wexford’s St. Martin’s at 3pm.

After retaining the county title in dramatic style, Na Fianna recorded a 3-20 to 1-15 win over Laois side Clough-Ballacolla in the quarter-finals.

St Martin's overcame Naas in their quarter-final, with Rory O'Connor racking up 0-11.

In the Munster football semi-finals, Kerry’s Dr Crokes are up against Waterford’s Rathgormack (1pm) and Clare's Eire Og Ennis’ take on Tipperary's Loughmore-Castleiney (1pm).

In the Ulster championship, impressive Armagh champions Clann Eireann take on Tyrone's Errigal Ciaran at 3.15pm, live on TG4.

Errigal Ciaran have several county stars in their ranks, including Peter Harte, the Canavan brothers - Darragh and Ruairi - and fellow Tyrone players Joe Oguz and Cormac Quinn.

But Clann Eireann, who dismissed Derry’s Newbridge last time, have plenty of star power of their own, with the likes of All-Ireland winners Barry McCambridge, Tiernan Kelly and Conor Turbitt.
