Dave Jones says the Owls can count themselves hugely unfortunate to emerge from Bolton with one point rather than a merited all three.
Wednesday dominated the Championship clash at The Reebok Stadium and were denied victory by a controversial disallowed goal in the second half.
Then, Jose Semedo was sent off near the end – much to the chagrin of the manager, who insists the midfielder’s tackle on Jay Spearing was not worthy of a straight red card.
He said: “You can tell by the reaction of the players and Jose is distraught because there is nothing wrong with the tackle.
“We know his game inside out and it is not his nature to go out and hurt someone. He has one foot on the floor and we will appeal the decision.
“Hopefully, the referee will look at it again and reverse the decision.”
Moving onto the disallowed goal from Jermaine Johnson, Jones added:
“There is nothing wrong with it from what we saw at the time and from what we have seen on the video.
“Jermaine heads it in but the assistant’s flag is up and there’s nothing we can do about it. We can’t get the goal back but we can get the sending-off rescinded on appeal if the referee changes his mind after seeing it again.”
Feeling hard done by aside, Jones was proud of his players, who turned in arguably their best performance of the season so far.
He said: “I am proud of them all. We were magnificent, we completely dominated the game and had chances to win it.
“Then when we do get what we feel is a perfectly good goal, we have it disallowed.
“I feel for the players and I feel for the fans, who were superb once again. They have seen us put on a performance today and these fans know when they see a performance.
“Everybody gave absolutely everything and we haven’t got what we deserved.”
