The Owls can confirm a pre-season friendly against League 2 side Scunthorpe on Saturday 13 July.
The game will take place at Glanford Park and is scheduled for a 3.00pm kick off.
Under the guidance of former Owls boss Brian Laws, the Iron will be aiming to bounce back to the third tier at the first attempt after suffering relegation from League 1 on the final day of the 2012/13 campaign.
