The Owls Under-18s face Premier League Leicester at Hillsborough on Friday evening in the fourth round of the FA Youth Cup (7:00pm).
Supporters are welcome to attend to cheer on the boys – entrance is free for Season Ticket holders, with prices for adults and concessions £3 and £1 respectively.
Wednesday have beaten Burton, Derby and Barnsley to reach round four, where the Foxes lie in wait.
Darren Moore is urging as many fans as possible to visit S6 tonight.
He said: “The Under-18s have another FA Youth Cup game here and so it's a message from me to the fans really to show support for them because they're on a tremendous run as well.
"Come and support them and see the next batch of talent that we've got on show. It will be a good game against Leicester.
"We need to be producing our own players. We've got one or two on the horizon and we'll keep pushing them."
