Stuart Gray says the Owls were good value for their 1-0 win over Middlesbrough on Saturday.
A late penalty from Atdhe Nuhiu was sufficient to give Wednesday a 12-point buffer from the drop zone in a game tinged with controversy.
The visitors were certain Danny Butterfield’s first half effort crossed the line after hitting both posts before the Owls’ claims for a penalty were waved away when Sam Hutchinson was flattened in the box.
Then it was the referee’s assistant who signalled a spot-kick on 86 minutes when Dean Whitehead handled a Leon Best shot on the line. The Boro man also received his marching orders.
Gray said: “I thought we deserved to win the game overall and came back well from what was a disappointing defeat on Monday night.
“We are talking about controversial moments again and I’m sure we would benefit from goal line technology filtering down from the Premier League into the Football League.
“It looked very close from where we were in the technical area but unless the referee is sure he cannot give it.
“It’s rather bizarre because we are talking about the same thing that happened on Monday night against Charlton.
“But until the technology comes into our league, we will continue to get these controversial moments.”
On the Owls’ penalty incidents, Gray said: “I thought the first one was stonewall if I’m being honest but you have to get on with it.
“The linesman gave the one that we did get and credit to him for that. They are there to assist the referee and that’s what he did.
“Credit too to Atdhe, he hasn’t had the best of times in front of goal recently and I had taken Chris Maguire off, and he is my penalty taker.
“But Atdhe struck it well under pressure, he hit the spot and you can’t ask for anything more than that.”
Gray also issued updates from the injury bay, with a string of players occupying the treatment table.
He added: “Joe Mattock came off with a thigh strain but Reda Johnson is back training with the squad and he will come into contention for Yeovil next week.
“Lewis Buxton played for the Development Squad in midweek but had a reaction to a hamstring so we will keep an eye on that.
“Michail Antonio is weeks away rather than days and Kieran Lee is still in the treatment room.”
