Derby match-winner Chris Maguire has told of the “huge lift” that the victory over Barnsley has given the Owls.
Boss Stuart Gray is also counting the cost of Saturday’s 1-0 win and pondering a possible move to sign a defender on loan.
Oguchi Onyewu limped off with a calf problem in the sixth minute of stoppage time, around a minute before Maguire buried a shot into the bottom corner.
Onyewu becomes the fifth centre half on the injured list.
But optimism within the club has soared now they are six points clear of the relegation zone, in 17th place, and have stretched their unbeaten run to 10 games.
Maguire said: “We looked at the table in the dressing room and it gave us a big lift. Looking at the teams in the bottom three, there’s a big gap between us and them.
“The main thing for us is to look forwards, not backwards. It’s a great feeling to have scored right at the end, and the win was a huge lift for everybody.
“I’m pleased with getting a goal, but most important is that it lifts the team up the table.”
He relived the build-up to his derby stunner: “You look up at the scoreboard and see time’s running out and you start to get a bit desperate. They tired a bit, they went down to nine men and started to get a bit sloppy at the back and gave us the opportunity to get the ball on the edge of the box. When Semi (Jose Semedo) gave it me, there was only one thing on my mind - to hit the strike, and thankfully it went in.”
Gray hopes that Glenn Loovens (hamstring) will be able to return at Reading on Saturday. But Martin Taylor (knee) and Kamil Zayatte (ankle) have suffered new setbacks, and Anthony Gardner (achilles) is still out.
The Owls boss said: “Glenn was touch and go. Hopefully he will be fit for Saturday.
“Hopefully Oguchi just cramped up. We’ll have to assess him. I keep saying I want to sign forwards; it looks like I’m going to have to get a defender in on loan.”
He also has Giles Coke still suspended, for the next two games, and Jermaine Johnson set to serve a three-match ban for his sending-off on Saturday.
Barnsley midfielders Emmanuel Frimpong and Jacob Mellis will serve bans of one and three matches respectively for their Hillsborough red cards.
