The Owls’ Under-18s were edged out 2-1 by Sheffield United in a dramatic derby encounter at Shirecliffe on Tuesday.
The Blades scored at the end of both halves and Mason Duffy’s effort for Wednesday ultimately counted for nothing.
The visitors started the game well, though, and George Hirst fired into the side-netting from an acute angle after finding space in the area.
Hirst then headed against the crossbar as the Owls pressed and Jonatas Centeno also went close.
But United opened the scoring against the run of play and came out for the second half in the ascendency.
The Owls had a penalty shout turned down in the early throes when Warren Clarke’s shot was seemingly handled but they did grab a deserved equaliser through the industrious Duffy.
Wednesday went on to pepper the United goal and had two shots cleared off the line before the hosts won it right at the last with almost the final kick of the game.
Wednesday: McDonagh, Brown, Stachini, Kirby, O'Grady, Lee, Centeno (Penney 57), Clarke (Price 73), Hirst, Duffy (Nicholson 89), Preston
