Newport County manager Justin Edinburgh blasted referee Richard Clark after his side's 4-1 defeat at Morecambe.
Edinburgh said the official had been "conned'' by Morecambe striker Kevin Ellison after he was brought down in the box for a 57th minute penalty which saw defender Tom Naylor sent off in a decision that he felt altered the course of the game.
County were leading one-nil at the time courtesy of Naylor but after Jamie Devitt levelled from the spot, Morecambe went on to score another three times in the second half to take all three points - Ellison on target before substitute Jack Redshaw bagged a brace.
Edinburgh said: "The referee was 20 yards behind play and he's been conned to be honest and it changed the match completely.
"Up until then our shape had been good and we hadn't really given Morecambe anything, but after the red card there were seven or eight minutes of madness from us and that wasn't good enough. We lost our concentration and from being in control of the game we were out of it.
"I'm disappointed for the lads and we certainly need to pick up some points sooner rather than later to get our confidence back but decisions like we had here certainly don't help. It will be tough but as long as we all stick together we will get through it.''
Naylor gave the visitors the lead with a 13th-minute goal but Morecambe levelled through Devitt's spot-kick after the controversial penalty decision just before the hour.
The home side then went on a goal spree with Ellison putting them ahead after rounding goalkeeper Ian McLoughlin just after the hour mark.
Shrimps substitute Redshaw then clinched the game with a fine header from 18 yards before adding a cool finish seven minutes from time.
Morecambe's victory could have been greater but for a superb save by McLoughlin as he tipped away a close-range Ellison header, before Redshaw came within inches of a hat-trick with a curled effort from the edge of the area which flew just past a post.
Morecambe boss Jim Bentley praised his side for the way they took advantage of Newport going down to 10 men - securing back-to-back wins after 10 games without victory.
He said: "We played some decent stuff in the first half without reward but once we got back in the game we were ruthless which was excellent.
"Two wins on the bounce has made a massive difference after going on a poor run of form and we are all looking forward to the next game now and hope we can build on two excellent results.
"I really wanted us to build on the victory over Southend at the weekend and we did just that, we are in a much better position now than we were this time last week.''
