Castleford had what many observers thought was a perfectly good try ruled out for obstruction by the video referee in the second half, and Dorn believed that had it been awarded, Cas would probably have won the game.
“That try got robbed off us – I don’t know how many times that’s going to happen to us,” the Australian full-back told Sky Sports.
“We put that to bed there, I think we win the game.”
Powell’s frustration was even more apparent, as he bemoaned the state of video refereeing in Super League at the moment.
“It was a try every day of the week,” he fumed.
“I’ve no idea what they’re doing. The game’s a joke when they’re doing things like that.
“There was no impact made. It was a ridiculous decision.
“At the moment it is a joke the way they’re making decisions on those things. I think they’re losing respect.
“I don’t think there is a coach in Super League who agrees with the way it’s being refereed and they need to change something. To disallow that was preposterous.”
Dorn, meanwhile, feels that the Tigers are getting closer to playing the kind of rugby which will serve them well in the play-offs.
“It’s finals footy, we’re getting close to that,” he said.
“If we keep playing like we are, we’re going to be in games like this.
“We’ve got to be better. We had opportunities to win.”
The main talking point from the game, however, was probably the red card handed to Leeds icon Kevin Sinfield, after he headbutted Dorn.
The Australian felt that such things happen when emotions are running high and the pressure is on.
“We got up and had a few nice words to say to each other. Sometimes these things happen on the field,” he said.
“I’d never seen it before. You could probably tell by the shock on my face that I was quite surprised.
“But that’s footy, it gets heated and you do some things, but there’s nothing in it.”
