Andy Farrell has made a last-minute change to his starting XV for the Six Nations showdown against Scotland at the Aviva Stadium on Saturday. Full-back Hugo Keenan has been ruled out due to a hip injury and Jordan Larmour will take his place in the team. Larmour, who earned his second cap of the tournament in the 36-0 win over Italy, replaces Keenan for the second time this season. Ireland only needs two points against Scotland to secure consecutive titles. Ireland's clash with Scotland is the highlight of the St Patrick's weekend festivities.
