Frank Murphy retains the captaincy in the absence of injured John Muldoon with the tried and tested partnership of Swift and Upton offering plenty of choice at lineout-time.
Ian Keatley will hope to add to his points total of 25, last week he became the top Connacht points scorer in a single Magners League match overtaking Paul Warrick's total of 21 against the Scarlets in 2006.
