Manager Lee Clark admitted Huddersfield only had themselves to blame after throwing a two-goal lead away in the 4-2 defeat at Peterborough.
The Terriers were in control at 2-0 up but an Alex Smithies blunder gifted Posh a lifeline just before the break and they took full advantage in the second half.
Clark said: "There is no doubt about it, we shot ourselves in the foot in the final few minutes of the first half.
"Up until that point we had played with intensity and stopped Peterborough from getting their more dangerous players on the ball.
"But in the last six or seven minutes before the break that changed and we paid the price by conceding. That goal will have given Peterborough a huge lift, but at 2-1 up we should have been able to push on.
"We conceded four very poor goals. The other three were not good defensively from our point of view, but I am not just pointing the finger at the back four. You should not put yourselves in a position when you need to score four to draw."
