Sheffield Wednesday can confirm details of the pre-season friendly in Slovenia next month against Serbian SuperLiga side FK Čukarički.
The Owls will face the Belgrade-based outfit on Wednesday 23 July during the five-day training camp which takes place between 19-24 July.
The game will be staged at the Ptuj City Stadium, which is 30 minutes away from the Owls’ training base in Maribor.
Kick-off time is still to be confirmed and will be announced in due course at swfc.co.uk.
FK Čukarički gained promotion to the Serbian top flight in 2012/13, securing the runner-up spot in the second tier and went on to finish fifth in their first season back in the SuperLiga and will now compete in the UEFA Europa League at the first round qualifying stage.
