Owls goalkeeper Keiren Westwood has made the final cut for the Republic of Ireland squad.
The 34-year-old is part of the 23-man squad for the double header against Gibraltar and Georgia after initially being named in the provisional squad.
The Republic are set to begin their UEFA Euro 2020 qualifiers away at Gibraltar (23 March) and at home to Georgia (26 March).
McCarthy is hoping to lead his team out of Group D, which contains Denmark, Georgia, Gibraltar, and Switzerland.
They begin with a trip to Gibraltar on Saturday 23 March at Victoria Stadium, followed three days later by a clash in Dublin at the Aviva Stadium against Georgia on Tuesday 26 March.
Westwood – who made 15 appearances for Wednesday this season - is in fine form for the Owls, who have kept seven clean sheets from their last ten Championship outings.
