Despite not being in Johnstone's Paint Trophy action this week, United will take their place in the second round draw at the weekend.
The Blades were one of 16 clubs to receive a bye in the first round, but will find out their second round opponents in Saturday's draw which will be screened live on Soccer AM on Sky Sports.
Ties will be played week commencing 8th October 2012.
Meanwhile, the Johnstone's Paint Trophy is set to make its seventh season of fan engagement the most vibrant yet, after laying down the gauntlet to clubs and supporters with the 'Johnstone's Paint Pot Challenge'.
To celebrate Johnstone's number one vinyl matt emulsion available in over 16,000 shades, the paint pot will be going on a nationwide tour throughout the 2012/13 season, visiting seven club training grounds for professional player challenges.
Designed to test the shooting accuracy of the most competent footballer, the challenge involves squad players trying to kick a ball from the half-way line into a huge inflatable paint pot placed within the 18-yard box.
At the end of the season, the club that records the highest number of successful player attempts will win £2,000 worth of Johnstone's product for a club makeover, along with a free consultation with Johnstone's technical support team.
Clubs that finish in second and third place will receive £1,000 and £500 worth of Johnstone's Paint product respectively.
Every last drop of paint pot action will be caught on camera and uploaded to the Johnstone's Paint Trophy website and social media channels, in addition to official club and Football League news sources.
Paul Farrell, sponsorship manager for the Johnstone's Paint Trophy, believes this year will be like no other for fan engagement.
He said: "There's nothing quite like going on tour and we believe that our Paint Pot Challenge is the new ace up our sleeve for interacting with fans. As we visit training grounds across the UK, we can't wait to see the reaction of players and supporters to the Johnstone's Paint Pot Challenge and get them excited about being part of the competition.
"We're always trying to come up with new initiatives to bring the Johnstone's brand, the trophy, clubs and supporters closer together, so what better way to do that than a battle of footballing prowess."
