Ireland head coach Andy Farrell has made three changes to the XV that beat Italy for Sunday's Guinness Six Nations clash against Scotland in Murrayfield.
Cian Healy and Rob Herring return in the front row, with the rest of the pack remaining unchanged, while Keith Earls is named on the wing, which is the only change in the backs.
Dave Kilcoyne, Ronán Kelleher and Jordan Larmour all drop to the bench, while Lions scrum-half Conor Murray returns to the bench at the expense of his Munster team-mate Craig Casey.
"Players are playing well and getting a bit more game time, coming up to speed. It was a difficult one this week but it's the right one for this game against Scotland," Farrell told reporters.
Kelleher had been heralded for his showing in Rome but Farrell insisted Ulster hooker Herring is the right man for the job.
"Rob is a great player for us," he said.
"He's a big leader in the pack as far as set-piece is concerned. He’s very accurate in that regard. His work-rate goes unseen quite a bit as well, as far as line-running, his numbers, his rucking.
"He’s an important part of our pack and he’s going to lead us from the start and then you look at what we’ve got on the bench.

"We’ve got a strong bench, dynamic bench that’s hopefully going to pay for us towards the end of the game."
Tadhg Furlong retains his place at tighthead, with James Ryan and Iain Henderson in the second row. As expected, Tadhg Beirne, Will Connors and CJ Stander, who will win his 50th cap, form the back row.
Jamison Gibson-Park and captain Johnny Sexton are the half-backs with Robbie Henshaw and Garry Ringrose in the centre.
"Conor has not played for five weeks, first and foremost, and Jamison has been playing really well so he deserves his start," said the former England centre about his scrum-half selection.
"He has progressed a lot since his first cap. He's had some pretty big experiences, going away to Twickenham, being involved in some big games.
"He is more comfortable in his role... he understands what it takes to be a top-class international scrum-half and deal with the pressure of the games. He’s thriving in the role.
Scotland's impression of Ireland 'irrelevant'
"He brings tempo, a little bit of off-the-cuff type feel to the game. He plays the game that’s in front of him. He’s dynamic, he’s got good footwork and he can ask questions of any type of defence.
"His game-control is pretty good so he’s a nice package to have."
Hugo Keenan once again starts at full-back with James Lowe named on the left wing and Earls back on the right.

"[Keith's] know-how, his organisation of the back line in all different aspects of the play," was what tilted the balance in Earls' favour over Jordan Larmour, said Farrell.
"He is certainly a leader in many regards of back field play and edge-defence play.
"He is great under the high ball, he is still as quick and sharp as ever. There is good competition with Jacob [Stockdale] coming back as well."
Ireland, despite a handsome win over Italy two weeks ago, are out of contention for honours following defeats to Wales and France.
Gregor Townsend's Scotland, however, can still challenge for a first title since 1999. They beat England in the opening round before losing to Wales.
Their scheduled game against France in round three was postponed due to a coronavirus outbreak in the French camp.
