Daryl and Didz set for crucial Euro qualifier against Christophe's Scotland
The Town striker is in contention to lead the line for the Republic in the Group D clash at the Aviva Stadium, kick-off 5pm.
David McGoldrick is also in the Irish squad, having won his second cap in last weekend’s goalless draw against England in a friendly.
Fellow Blue, Christophe Berra is in the Scotland party for a game the Republic really need to win.
They sit two points behind Scotland in fourth place, with Poland and Germany holding down the top two spots in what is a highly competitive qualifying group.
Town midfielder Kevin Bru is also on international duty with Mauritius, who play Ghana in their Africa Cup of Nations qualifier on Sunday.
