Stuart Gray is incredulous over the decision that prevented Wigan from going down to 10 men before they pulled off a 1-0 win against the Owls last night.
The Wednesday boss insists that Latics keeper Ali Al Habsi should have been sent off for bringing down Jacques Maghoma.
Al Alhabsi was only booked and saved the penalty that resulted from his challenge - Leon Best took it, in the 37th minute.
Gray said: “It was definitely a red card. I couldn’t believe it when the referee has pulled a yellow card out.
“Jacques Maghoma’s got the ball under control, more or less gone round the keeper and he’s just wiped him out. When the ref has brought out the yellow card, I was amazed.
“Then the keeper’s pulled the save off that stopped us from taking the lead. We shoudn’t be missing a penalty, but it would have been a totally different game against 10 men.”
Gray had no complaints about the decision that gave Wigan an 88th minute penalty winner after a challenge by Caolan Lavery on right back James Perch.
The Owls boss said the team’s performance was “100 per cent better” than the one that resulted in defeat at Yeovil: “Like I said to the players, I don’t want to get into the habit of getting beaten, but if you’re going to get beaten, then it’s after you’ve had a right good go.
“We controlled Wigan, nullified them, we mirrored their shape. It’s a quiet, very disappointed and upset dressing room, thinking of what might have been.”
