Huddersfield interim coach Luke Robinson described Hull FC’s match-winning penalty as a ‘really tough’ call.
Marc Sneyd kicked the decisive goal after second-rower Kenny Edwards was penalised for not being square at the marker marking position.
However, Robinson thought the call was harsh as his side fell to back-to-back defeats.
He said: “It looked as though Kenny Edwards played a single marker system. He was square in front of him. The ball actually cleared the ruck and he was a little bit slow to keep up with the nine.
“I think that is what probably made it look worse than what it was because the nine was a little late in picking the ball up.
“It looked as though Kenny has jumped around it but I will let others be the judge of that, but I did think the call was really tough.”
Robinson’s side remain in sixth place in the table but now face an almost impossible task to make the end-of-season playoffs.
Speaking further on the narrow defeat and where it leaves his side going forward, interim boss Robinson said: “Hopefully the percentages favour us to win our next close game.
“They are a little more heart-breaking are these types of defeats.
“These scorelines are hard to take. When you get beat by one of two points it very much reminds me a bit of 2008, in my first year at the club, when we lost five games by two points or less.
“We came tenth that year and then next season under Nathan Brown, we won the next five games by two points or less and then we came third.
“It is not just the points on the board, it is also the confidence it gives you.
“You feel like you are playing a bit better when you pick up these wins and when you lose, you feel worse than what you are.
“We have to find a way back. Professional rugby league is all about inches and fine margins.
“When the pressure is on, we have to manage things a bit better.”
