Garryowen facing a test of mettle in battle with Clontarf
Young Munster were not able to derail Old Belvedere's title charge last weekend, but this week it's up to Garryowen to throw a spanner in the works of Clontarf's intentions.
The Cookies fell to a 34-12 defeat at Anglesea Road last weekend, but they will fancy their chances of pulling off an away win at Ballynahinch.
Garryowen – basement boys all season – have pulled level with Ballynahinch at the bottom of the table after a 12-8 win against Cork Con. Andrew O'Byrne kicked four penalties for the hosts; Con responded with 71st-minute try from Ryan Foley.
A fourth win from five would be a huge boost to Garryowen as they seek to retain their division 1A status, while Con will hope to get back to winning ways at Lansdowne (2.00pm).
Dolphin suffered a heavy defeat to UCD last Sunday, but face a tricky test again tomorrow when they meet St Mary's College at Templeville Road.
In Division 1B, a Robbie Burke penalty a minute from time gave UL Bohs the honours in the Limerick derby against Shannon.
Both sides still retained slender chances of promotion entering the tie, but despite having a game in hand on their neighbours, Shannon now look too far removed for a late run.
Bohs can boost their chances with a win at second-placed Corinthians, while Shannon face a tough home test against leaders Terenure.
Last weekend's defeat to Queen's University means Bruff have suffered consecutive relegations, so UCC's quest for points is all that's up for grabs at Kilballyowen Park. Highfield need a win at Naas if they are to avoid the same fate as their Limerick neighbours; Old Crescent are another side in need of points when they welcome Cashel to Rosbrien.
Nenagh Ormond will clinch promotion and the Division 2B title if they manage to beat Suttonians at New Ormond Park, while victory for Thomond against Midleton will keep them in the hunt for the second place.
Sundays Well travel to Boyne, while Richmond face a trip to Skerries, fresh from their 15-10 win against Suttonians last week.
