Salford coach Iestyn Harris was unhappy with the way in which he felt Wigan benefited from a refereeing error at the DW Stadium on Friday evening.
The Red Devils were beaten 19-12 after leading 12-0 early in the second half. A Dan Sarginson try saw Wigan go into the lead.
There was some doubt, however, about whether Sarginson got the final touch on a Michael McIlorum kick ahead.
“The in-goal touch judge gave a drop-out. He is right there on the spot and he (the referee) goes with a touch judge that is 20 metres away,” said Harris after the game.
“That was frustrating for us and disappointing but it’s Wigan away. I’ve been in that dressing room and you tend to get those decisions when you are in that dressing room.
“Wigan threw a lot at us and we defended reasonably well. We repelled a lot of what they threw at us and a couple of ricochets got us.
“We certainly have to do a lot of improvement with ball in hand but the attitude of the players was spot on.”
