The game against the Championship side is their first stand alone game of the pre-season schedule and will take place on Saturday 1 August, with a 3pm kick-off.
United, who are now managed by former Wigan boss Uwe Rosler, finished 15th last season in a disappointing campaign filled with controversy.
The last time the two sides met was a League Cup tie in September 2012 with Leeds running out 2-1 victors on that day. They last met in the league back in 2004, with James Milner equalising a Wayne Rooney opener.
It is refreshing however, to see Roberto Martinez's side taking on challenging opposition this time around, with it hopefully reaping rewards come the beginning of the campaign, with last year's pre-season proving to be a shambles.
