Chris Thorman hit out at referee James Child after seeing his Huddersfield side lose to Salford.
The caretaker coach watched on as the Giants conceded 10 penalties in their 30-12 defeat to the Red Devils.
Huddersfield’s misery was compounded when Danny Brough was sent off late on for dissent, and Thorman was in no mood to cut Child any slack either following the match.
“I honestly believe it’s the most baffling refereeing display I’ve seen so far this year,” Thorman said.
“I was scratching my head a few times over some of the decisions that were being made. I’m a coach and I know the sport, and I shouldn’t be left scratching my head over such decisions.
“Obviously, this is out of my hands and we’ll continue to focus on putting the things right that are directly within our control, but what we saw out there in this game from the officials was a cause for concern.”
Brough is thought to have been dismissed following an interaction with a touch judge, with Thorman expressing his hope that there would be no further action.
“Hopefully it will be sending off sufficient,” he said.
“It’s not for me to do their job, it’s not for me to do James Child’s job either but I’d have a decent crack.
“Broughy had a real crack and he got a bit agitated. You need your most experienced players on the field if you are going to win games.”
On the performance, Thorman said: “We made 13 unforced errors in the game, and you can’t really expect to be able to compete on the back of something like that. We made the mistakes and Salford hit us with the sucker punch.
“Making that number of errors obviously concerns me, but to too does the way in which this game was handled by the referee.”
