Although Cork Constitution were beaten and Shannon weren't playing, they will still have home advantage in the semi finals against Bucaneers and Belfast Harelquins respectively. Con's conquerors, Lansdowne ensured their place in the top tier with that 18-0 win on a muddy back pitch at Lansdowne Road, their final try coming in injury time from Stephen O'Connor but at a time when the outcome was beyond any doubt. All the incentive was in the Lansdowne camp who knew they needed a win to avoid relegation while Con were already home and hosed.

Dolphin and St Mary's both managed to pick up bonus points but both are relegated with Galwegians sealing the fate of the Templeville Road side thanks to a 19-13 victory over Brent Pope's side.

In Division Two, Old Belvedere dropped from first to fourth after they were blitzed in the opening half by UL Bohemians - who led by 24 points - at Thomond Park and Dublin University took full advantage gaining full points with a 34-3 over Sunday's Well to earn themselves division one football next season.
