Dúbravka currently has 11 caps for his country, but could get the opportunity to add to that figure next month as Ján Kozák’s side play a friendly before their opening UEFA Nations League clash.
Slovakia welcome Denmark to the Stadion Antona Malatinskeho for a friendly on Wednesday, 5th September (kick-off 7.45pm).
They then take on Ukraine in their first fixture in the inaugural UEFA Nations League at the Stadion Lviv on Sunday, 9th September (2pm kick-off).
And Dúbravka, who joined United on a permanent deal earlier this summer, could line up alongside a former Newcastle player in those games, with defender Lubomir Satka also named in the squad.
Twenty-two-year-old Satka made one senior appearance for the Magpies, in an FA Cup tie at Leicester City, before leaving for FC DAC in 2017.
