Full live coverage of the match is on STV from 1.25pm
Scotland travel to Dublin for a crucial Six Nations showdown on Saturday with both sides still in contention to win the championship.
Ireland remain undefeated as they chase a grand slam while Gregor Townsend's men will be buoyed by their Calcutta Cup victory against England last time out at Murrayfield.
The Irish can secure their third Six Nations title in five years on Saturday provided they beat the Scots with a bonus point and England fail to achieve the same outcome in Paris.
Scotland still have an outside chance of lifting the trophy but will have to improve their away form having only ever won two Six Nations away games outside Rome, once in Cardiff in 2002 and more recently in Dublin eight years ago.
Can Townsend's men halt Ireland and keep their own title hopes alive?
Gregor Townsend is sticking with a winning team after back-to back home victories over France and England as he only makes one change to his starting XV.
Edinburgh back Blair Kinghorn steps in for the injured Tommy Seymour to take his place on the wing as Warriors winger Seymour still recovers from a back injury.
The 21-year-old made his debut as a replacement in the win over England and this will be his first start in a Scotland jersey.
On the replacements bench, Glasgow Warriors winger Lee Jones fills in for Kinghorn, with the only other change to the bench coming with hooker Fraser Brown replacing the injured Scott Lawson.
The Scots must win to keep their title hopes alive and set-up a thrilling final day finish in Rome.

Furlong will replace Andrew Porter at prop after returning from injury with Ringrose coming in for the injured Chris Farrell.
Ringrose will partner Bundee Aki in the centre while Conor Murray and Johnny Sexton remain as the halfbacks.
Ulster lock Iain Henderson returns as a replacement as James Ryan and Devin Toner remain in the starting line-up.
