Jamison Gibson-Park retained his place in the Ireland side, while Sean Maitland and Jamie Ritchie will return for Scotland in Sunday's Six Nations encounter at Murrayfield.
Gibson-Park started the loss to France and victory over Italy, with Conor Murray ruled out, and the scrum-half did enough to retain the number nine jersey.
Murray is back on the bench along with Jordan Larmour, who is replaced on the wing by the experienced Keith Earls.
Prop Cian Healy comes in at loosehead at the expense of Dave Kilcoyne, who is named among the replacements as Andy Farrell's men attempt to make it two wins from four in the tournament.
Gregor Townsend has made four alterations to his line-up for Scotland's first match in a month after their clash with France was postponed due to a coronavirus outbreak in Les Bleus' camp.
Wing Maitland and flanker Ritchie return from injury, replacing Darcy Graham and Blade Thomson respectively.
Zander Fagerson's suspension gives prop WP Nel the chance to start, Sam Johnson makes his first appearance of the tournament in place of James Lang.
Grant Gilchrist and Nick Haining will be ready to feature in the 2021 Six Nations for the first time from the bench.
