The Owls’ Under-21s went down 3-1 to Huddersfield in the Professional Development League on Monday night.
The Hillsborough clash produced chances at both ends, with the high-flying visitors the more clinical to earn the win.
The Terriers struck first with just five minutes on the clock when Joe Lolley embarked on a mazy run that took the midfielder past three challenges before firing home across Cameron Dawson.
Wednesday responded in kind four minutes later as Ryan Croasdale linked up well with Mani Dieseruvwe and the latter drilled into the back of the net.
That was as good as it got for the Owls in front of goal as they went close through Caolan Lavery and Rhys McCabe.
But Huddersfield led the way and restored their lead seven minutes before half time with a crisp finish from Duane Holmes.
Dawson kept the Owls in the game on 56 minutes with a stunning save to deny Danny Carr but the keeper could do little to keep out the same player moments later after good work from Holmes.
Wednesday created further openings via Lavery and Jack Stobbs but failed to work Terriers keeper Lloyd Allinson and the points belonged safely to Town.
Owls: Dawson, Young, Floro, De Haviland, Sanders, Lee (Stobbs 61), McCabe (Meadows 46), Croasdale, Lavery, Hanna (Beatson 72), Dieseruvwe
