The Owls will host Premier League Everton in the third round of the Carabao Cup on Tuesday 24 September.
The cup-tie with the Toffees will kick-off at 7.45pm.
Wednesday progressed in the competition after defeating Rotherham 1-0 at the New York Stadium in midweek, as Atdhe Nuhiu’s injury time strike sealed the win.
Everton, meanwhile, came from behind in their trip to Lincoln to win 4-2 at Sincil Bank.
It will be the first meeting between the two sides since September 2007.
Ticket detail will be announced in due course.
