Scottish giants Rangers will visit Hillsborough for a prestigious pre-season friendly for the Owls.
The fixture against the Glasgow club will kick-off on Wednesday 24 July at 8.00pm.
Rangers, under the guidance of boss Ally McCoist, are aiming for a speedy return to the Scottish top flight after demotion to the basement tier in 2011/12.
McCoist’s men romped to the title last time out.
The Ibrox outfit were comfortable winners of the third division in 2012/13 – finishing 24 points ahead of second-placed Peterhead.
The warm-up clash with Rangers will be Wednesday’s only friendly on home soil ahead of the 2013/14 campaign.
Ticket details will be announced in due course.
