Wednesday await their FA Cup fifth-round tie against Charlton with the quarter-final pairing with United having given them an extra incentive.
Both Sheffield clubs will have hopes of a Wembley semi after they avoided the Premier League clubs in the quarter-final draw.
A new date for the Owls’ game that was postponed on Saturday has yet to be announced - but they now know that if they beat Charlton they have have a trip to Bramall Lane on the weekend of March 8-9.
The quarter-final draw also ruled out a repeat of the 1993 Wembley semi, which was won 2-1 by the Owls.
In the meantime Stuart Gray is preparing for a big home Championship match tomorrow against promotion-chasing Derby.
The Wednesday boss has shrugged off the prospect of further fixture congestion after the postponement of the match against Charlton.
The new date will have to be placed into an already crowded programme but Gray told The Star: “We just have to get on with it. If you’d said we’d still have a chance of the quarter-finals and it meant we’d have a fixture backlog, anybody would have taken that.
“It was disappointing that the game was off, but it was the only decision that could be made.”
The only benefit to the Owls was that it gave the players a break before tomorrow’s home game against Derby and it perhaps allowed a little more time for Glenn Loovens to make sure that his hamstring problem has fully cleared up.
“It may have helped us in that respect but it may also benefit Charlton as they’ve probably got injuries as well,” added Gray.
The Owls trained on Saturday morning after the Charlton game was called off because the Hillsborough pitch was waterlogged.
