STEVE Lomas felt his Millwall side were once again on the wrong end of some poor refereeing decisions during their 3-1 defeat at Bolton.
Lomas was unhappy that referee Graham Scott ignored a head injury sustained by Nicky Bailey in the build up to Rob Hall's opening goal in just the fifth minute of the match.
And he felt the visitors had two strong penalty claims dismissed.
But the Northern Irishman admits the Lions, who now have the joint-worst defensive record in the Championship, must tighten up at the back.
"I'm bitterly disappointed about the first goal," he said. "It is clearly a head injury and the fourth official said that into his mic five times, but the referee's earpiece wasn't working.
"But the referee saw the incident and still didn't call it. It is probably the first time this year I've seen play waved on when a player has a head injury.
"It's a key position for us because Nicky offers us some protection in front of our back four. We seem to be getting the short end of the stick more times than not when it comes to decisions.
"I spoke to the ref and he said his earpiece wasn't working, but that's irrelevant because he saw the incident and didn't think it was a head injury.
"We had a couple of penalty claims turned down as well.
"We had a handball claim where Justin Hoyte goes inside Alex Baptiste and it hits his hand – you maybe get them one week but the next week you don't.
"The challenge by Medo on Martyn Waghorn was definitely a penalty because he didn't win the ball and his foot was high. It's a free-kick in any other area of the pitch."
But Lomas said Millwall only had themselves to blame for losing the match, having hauled themselves level through Jermaine Easter's second goal of the season.
And he was particularly frustrated to concede a second goal before the interval.
He said: "We regrouped and showed courage and resilience to get back in the game – only to shoot ourselves in the foot. To get back to 1-1 with four minutes until half time, you've got to see it through.
"At 1-1, the second half would have been difficult for Bolton but they were able to sit deep and soak up pressure. We were growing into the game so we hurt ourselves. We can't keep coming back from behind.
"There was a lot of good stuff but we've got to get tighter at the back and stop conceding silly goals at crucial times. We have to give ourselves more of a chance in games.
"We're not far away but we're conceding poor goals at critical periods. We kept the ball well in the second half but we could have been a little bit more creative."
