STEVE Lomas criticised the performance of referee Lee Collins after his side's 5-2 defeat to Bournemouth on Saturday.
The Lions were reduced to ten men early in the second half when right back Alan Dunne was shown a second yellow card following a handball in the area.
The visitors had already thrown away a two-goal lead by that stage, and former Den striker Lewis Grabban converted the resulting penalty to put the Cherries in command.
Lomas said: "At 2-0 we were coasting and probably could have scored a third goal through Lee Martin. A mad 15 minutes totally reversed the game but I thought we got some poor decisions from the referee.
"It is a flick on that hit Alan's hand – it was right down by his side, how is that a deliberate handball? It's one thing to give the penalty, but to send him off was extremely harsh.
"There was a tackle by Ryan Fraser on Paul Robinson that was a straight red card. I don't know how the referee doesn't see it that way when he's booking every tackle we make.
"I'm not saying it's because of the ref that we lost the game, but he has certainly contributed into making it very hard for us."
Lomas admitted it was hard to fathom just how his side had collapsed, having been in such a strong position after Martyn Waghorn and Liam Trotter scored inside ten minutes.
"The goal just before half time gives them a bit of momentum but we've got to weather the storm," he said. "We had a shocking 15 minutes that took us out of the game – three goals and a sending off. It was quite mad really.
"Everything was looking good in the first half but we lost a bit of concentration and were sorely punished. It is concerning. That's nine goals we've conceded in our last two games.
"We've got to pick ourselves up and go again. It's never good to have an international break after a heavy defeat, especially when we had the game almost won."
The visiting fans were chanting 'Lomas Out' at the final whistle but the Millwall boss does not feel as though his job is under threat.
"It is part of football," he said. "After a heavy defeat you are always under scrutiny – it's Dougie Freedman one week, me the next and it will be someone else the week after."
