Hull Kingston Rovers coach Craig Sandercock blamed a lack of discipline coupled with individual errors for the 38-34 defeat at Salford.
The Robins had looked to be in control of the match having a 20 point cushion going into the last half an hour but Salford showed spirit and determination to comeback and win the encounter.
The defeat means Sandercocks side have only won one of their opening four games in Super League leaving the club in eleventh position.
The coach was left disappointed at the errors and told the Hull Daily Mail “It’s different players making the mistakes every week. if it was the same player week after week, I could do something about it.
“All the other errors we made were disappointing, and of course, I expect better. In the end, if we had been disciplined and not given away all those penalties and kept hold of the ball, we’d have won the game. It’s that simple.”
