Tickets can be purchased online or from the ticket office at the Proact Stadium.
Meanwhile, any Sheffield United fans who have purchased tickets for areas of the stadium reserved for home fans are warned that they face being ejected.
Stewards will be looking out for any Blades supporters who are seated in home areas. Any who are found to be in the wrong area will be escorted from the stadium.
