Fans trying to get through to buy tickets for Sheffield United's up and coming games hit a snag due to a power cut.
Technical issues with the ticketing system at Bramall Lane occured this morning as fans queued in the South Stand car park hoping to secure tickets for tomorrow's clash with Coventry City plus a televised beam back for the Blades' trip to Northampton and the Kell Brook fight in May.
United could clinch promotion to the Championship if they beat the Sky Blues and 3rd placed Fleetwood fail to beat Oxford.
Online sales were also affected but this has now been resolved.
Bosses at the club said they would keep the ticket office open until 7pm for fans due to the earlier technical problems.
A spokesman from the Blades said: "The Ticketing System is now back online, sales are being taken in person and over the telephone."
