Cian Kelleher comes in on the wing in place of Adam Byrne while Jack O’Donoghue has recovered from the knock he took late in the opening fixture to take his place in a side that features 10 Leinster players, three from Munster and just one each from Ulster and Connacht.
“An unchanged side gives us some consistency and will allow combinations to develop across the field. We have some fresh faces on the bench which will be hoping to make an impact at some stage,” said Ruddock.
