Sammon is set to make his senior international debut at the Aviva Stadium in Dublin on Wednesday night after head coach Giovanni Trapattoni confirmed his starting line-up for the match on Tuesday afternoon.
The 26-year-old, who has scored seven goals for the Rams this season, will partner West Brom's Shane Long up front.
Sammon's Derby team-mates Richard Keogh and Jeff Hendrick, also called up to the senior set-up for the first time along with Sammon, have missed out on starting spots but are expected to be on the bench.
Team: David Forde; Paul McShane, John O'Shea, Ciaran Clark, Greg Cunningham; Robbie Brady, James McCarthy, Glenn Whelan, James McClean; Shane Long, Conor Sammon.
