There are also two Ireland v Scotland clashed on Friday with Connacht travelling to Edinburgh and Glasgow going to Ravenhill to face Ulster. This will be Ulster’s first home game since the first week of the year and they will be hoping that the return home will bring an improvement in their fortunes after three defeats in both the league and Heineken Cup.
With the Rugby Aid game, which features several Celtic League stars, at Twickenham on Saturday afternoon there is only one game on Saturday with Munster looking to keep up the chase on The Neath Swansea Ospreys when they face Cardiff Blues at the Arms Park.
On Sunday the leaders face Leinster with the Ospreys hoping to inflict a fourth league defeat in their last five games which will keep them well clear at the head of the table.
