KENNY Jackett criticised referee Gavin Ward after Millwall's controversial 2-1 defeat to Blackburn Rovers at The Den on Tuesday.
Ward gave the visitors a penalty in the second half after Grant Hanley went down, with Mark Beevers close by, but replays showed the centre-back had not received any contact from a Lions player.
Jordan Rhodes converted what proved to be the winner from the spot to leave Jackett's side still in danger of relegation with three games of the season remaining.
"I have seen it again and it did look a very soft decision," Jackett said. "In my opinion, the referee got the assessment wrong. It didn't look as if there was any contact. I felt it was very harsh.
"I was looking for the team of officials to make the right call because it was a crucial moment in the game. I've not spoken to the referee – it's something that I'll probably do.
"Having said that, I can speak to him all I want – it is not going to change anything. We have not got anything from the game but a draw would have been a fair result."
Despite his frustration with the referee's decision, Jackett was equally critical of Millwall's defending in the build up. He said: "We were chasing the game and were too gung-ho.
"It's a good run by Hanley but he shouldn't power through like that from one end of the pitch to the other. It's poor. There were too many people on the wrong side of the ball."
Captain Danny Shittu was booked for dissent in the immediate aftermath of the incident and then received a second yellow card after the full-time whistle.
"I was in the dressing room at the time but Danny informed me when he came in that, whatever he said, the referee deemed it to be worthy of a booking," Jackett said.
"Danny is upset and I have to back my player. It is not something I want – I do not want him to miss any games – but he's been fantastic for us and is a passionate man. We have to swallow that one.
"He's in a situation where he felt very passionately that there was no contact."
Prior to the penalty, Karleigh Osborne's opener had been cancelled out by Rob Hulse's own goal – a deflection on the line from David Jones' corner.
But Jackett felt the Lions were in a good position to get something out of the game with the score at 1-1. He said: "I wouldn't say we did enough to win but we deserved a point.
"We started the game very well. After 35 minutes Blackburn came into it strongly – David Dunn was very influential. Their first goal was very disappointing. That shouldn't happen in this division.
"Once we made two substitutions at 1-1, we got a foothold back in the game when it looked to be going away from us. With that foothold, I didn't think we did enough to win but it looked even.
"We went down battling and fighting at the end by putting Blackburn under pressure and getting balls into their box. But ultimately, the decision has cost us."
