Norwich City manager Paul Lambert was left angered with the officials after his side's 1-0 defeat at Stoke City.
Matthew Etherington's 72nd-minute goal came from a throw-in that looked like it should have been awarded the the Canaries.
"I think it was our throw," said Lambert. "[Referee Michael Oliver] is walking away as if he has given it to us, and he actually raises his hand a little bit as if it is a Norwich throw, and then the linesman has overruled him for some reason.
"Our lads think it is our throw, we are out of possession and then we lose a bad goal. I think it was there for everybody to see that it was a Norwich throw.
"[Oliver] did admit it to me in the tunnel that he was going to give it to us, but the linesman has overruled him."
The defeat has left Norwich 10th in the Premier League table.
