Wednesday were beaten 4-2 at home to Crystal Palace on Saturday at Middlewood Road.
The Owls started well with Franck Betra putting the hosts ahead after just four minutes when he guided into the bottom corner from the edge of the box.
But Palace were soon on terms when Jacob Berkeley-Agyepong cut in from the left and struck the ball past Wednesday keeper Joe Wildsmith.
The remainder of the first half saw a very open game with both teams having chances but it was Palace who took the lead on the stroke of half time, Ibby Akanbi scoring after a goalmouth scramble.
The Owls came out fighting in the second half but they conceded a contentious penalty, which Eujah Gabsi converted on 53 minutes.
But Wednesday immediately got themselves back into the game after Charlie Dawes beat firstly three defenders then the goalkeeper to score from 20 yards.
Palace made two substitutions, one of whom - Kyle Spence – put his side out of reach with a well-taken goal.
Owls coach Steven Haslam said: “We took the lead early on but then we needed to be more clinical with the chances we had before allowing them back into the game.
“Some poor decision making and lapses of concentration made it difficult for us to win the game.
“The positives are that we created plenty of chances but we have to be more ruthless.”
