The Falcons host Jordan in Trnava for a friendly on Friday, 7th June (kick-off 7.30pm BST) before the squad is cut down to 23 players ahead of their Euro 2020 qualifier against Azerbaijan in Baku on Tuesday, 11th June (kick-off 5pm BST).
Slovakia sit in top spot of Group E after beating Hungary 2-0 in their opening qualifying clash but slipped to a 1-0 defeat against Wales back in March, with Dúbravka in between the sticks for both matches.
The 30-year-old, who has 17 international caps to his name, made eleven clean sheets for the Magpies this term and could line up alongside former Newcastle player Lubomir Satka, with the defender also named in the squad.
Twenty-two-year-old Satka made one senior appearance for the Magpies, in an FA Cup clash at Leicester City, before leaving for Slovakian outfit FC DAC in 2017.
