The Owls’ Under-18s recent run of resistance finally came to an end on Saturday when Huddersfield emerged triumphant from Middlewood Road by the odd goal in three.
It did seem as though Wednesday were heading for another win as they led through Mason Duffy's first half opener until the last minute.
But a late double from the Terriers denied the Owls and handed Huddersfield an unlikely win.
It was harsh on a young Wednesday side, who were denied a seventh straight clean sheet right at the last.
Owls: McDonagh, Foster, Stachini, Clarke, Penney, Beatson, Conneh (Lonchar 81), Brown, Hirst (Tracey 70), Ellam (Law 64), Duffy
