O'Donnell handed Ireland start, three changes for Scotland
Tommy O'Donnell has been included in Ireland's starting line-up for their final game of the Six Nations on Saturday, while Scotland head coach Vern Cotter has made three changes to his side for the encounter in Dublin.
Munster flanker O'Donnell is preferred to Josh van der Flier at openside in the only alteration to the team which started the hammering of Italy last weekend.
Captain Rory Best has been passed fit for the match at the Aviva Stadium after recovering from a calf injury, while Cian Healy and Eoin Reddan have to settle for a place on the bench.
Scotland stand-off Duncan Weir will make his first start of the tournament after he got the nod over Peter Horne in the absence of fly-half Finn Russell, who suffered concussion in the defeat of France last Sunday.
Lock Tim Swinson also gets his chance from the start in the absence of Jonny Gray (pectoral tear), while Ryan Wilson comes in at number eight at the expense of Josh Strauss - who has been named among the replacements.
Scotland will be eyeing a third win in a row which would most like seal third place with second-placed Wales expected to beat Italy. Ireland are just a point behind Cotter's men in fifth after just the one win against Italy.
