The Ireland-Georgia game will be streamed live here: http://www.eurorugby2014.pl/en/gallery/.
Calvin Nash, a try scorer that day, and Paul Kiernan come into the back-line on the right wing and at outside centre respectively.
Jordan Larmour and Alan McMahon drop to the replacements bench, with Jacob Stockdale, who touched down twice in the number 13 jersey against the Scots, moving to the left wing.
Matthew Gilsenan and Rowan Osborne continue their half-back partnership, while the starting pack is unchanged with James Ryan captaining the side from the second row.
An Irish win over Georgia would set up a clash with either France or Italy next Tuesday. Ireland's final match of the tournament will take place on Saturday week.
The competing nations in the Elite Division of the FIRA/AER European Championship are Ireland, England, Wales, France, Scotland, Italy, Georgia and Portugal.
The Irish squad is coached by Noel McNamara (head coach), Mark Butler (backs coach), Brian Robinson (forwards coach) and Paul McCarthy (scrum coach).
