A new date has been arranged for United's visit to Crewe Alexandra - which was originally scheduled for Tuesday but postponed due to a frozen Gresty Road pitch.
The Blades will now travel to Cheshire on Tuesday 23rd April - the final week of the regular npower League One - with a 7.45pm kick-off.
The re-arranged date will fit in between a trip to Portsmouth and the home encounter with Preston North End, the final game of the league season. Tuesday's fixture was postponed after a local referee deemed the Gresty Road surface was unplayable at a midday pitch inspection.
Original tickets will be valid for re-arranged fixture, any supporters unable to make the new date can obtain a refund from the Ticket Office in advance of the match.
