Rob Kearney will miss Ireland's final game of the Six Nations on Saturday, while Scotland have injury concerns over Finn Russell and Jonny Gray ahead of the clash in Dublin.
Full-back Kearney was ruled out of the 58-15 hammering of Italy last weekend and will not face Vern Cotter's side as he is still being troubled by a hamstring injury, so Simon Zebo looks set to keep his place.
Ireland head coach Joe Schmidt said: "That hamstring is still niggling him and it just means that it would be a risk to push him on this week, so we've decided to leave that, to let him rehab it fully.
"He's probably only a week or two away, but that's probably a little bit too tight for us to make a decision here and now, so we'll leave Rob at this stage and give someone else an opportunity."
Schmidt added: "Apart from that, we actually came out of the weekend pretty well unscathed: a few stitches, a bloody nose for Andrew Trimble.
"But apart from that everyone else came through okay and Cian Healy [hamstring] and Eoin Reddan [calf] look like they're pretty well ready to go for probably tomorrow's [Tuesday] training and if that goes well then they'll come into the reckoning for selection as well."
Scotland stand-off Russell must undergo the graduated return to play protocol after suffering a concussion early in Sunday's 29-18 win over France at Murrayfield.
Gray is to be have a scan on Monday as the towering lock is being troubled by a pectoral strain, while Scotland have a number of other players who are being treated to ensure they are fit to face Ireland.
