Swansea 1-1 QPR: QPR Manager Neil Warnock felt referee Lee Probert made a mistake in not disallowing Swansea's opening goal in the Barclays Premier League draw at the Liberty Stadium.
Warnock had seen Danny Graham appear to handle the ball in the build-up to his goal before Jamie Mackie earned the visitors a point in the second half.
And he said afterwards: "I'm disappointed that we haven't got three points.
"We got the stuffing knocked out of us. The referee saw it was handball but said it was not intentional.
"It was a crucial decision, a big decision like that. You've got to know the game."
Asked for his opinion on Probert's performance Warnock replied: "He was consistent right from the first minute to the last."
Swansea scorer Graham disagreed with Warnock and also claimed he should have been awarded a penalty for a foul by Armand Traore.
Graham added: "It definitely was not deliberate (handball). I think we had a good claim for a penalty in the second half which we were unfortunate not to get."
Graham said Swansea were unhappy about being pegged back by Mackie's goal after dominating the first half.
"We're probably a bit disappointed with the way they scored the goal, it was a big punt up field."
Graham has begun to settle into the Swansea style of play which has brought him six goals in 11 games.
"I'm just getting used to the style of play. I've come from Watford who play a different style."
Mackie scored for the second game running to earn that deserved point.
The Scotland winger coolly slotted home a 58th-minute equaliser after Leon Britton's defensive header had slipped between his own defenders to allow Mackie in on goal.
Swansea had led from the 14th minute thanks to Graham's sixth goal of the season.
The striker was given too much time to control a Wayne Routledge cross - albeit with the apparent use of his arm - before turning and firing low into the net as QPR defence appealed in vain for handball.
It took a great block by Hill to deny Graham a second as the striker waited to pounce on Scott Sinclair's ball across the box, before Vorm made a flying stop to keep out Barton's effort from distance.
At the other end Helguson was guilty of poor finishing as he headed over twice in quick succession from crosses by Young and Barton as the interval approached with QPR in the ascendancy.
