Stoke City manager Tony Pulis criticised referee Martin Atkinson following Saturday's 2-0 Premier League loss at Sunderland.
He felt his Potters side failed to receive the rub of the green at the Stadium of Light as Asamoah Gyan's double sealed the points for the Wearsiders.
But the game's controversial moment arrived in the 71st minute when former Black Cats forward Kenwyne Jones' header appeared to be cleared off the line by Lee Cattermole's arm.
Stoke's staunch appeals were turned down and defender Ryan Shawcross was then dismissed, before Gyan added a late second to complete the triumph, leaving Pulis pondering another tough call.
"The decision again is game changing," he said."That is the sixth bad decision in 11 games against us.
"It is handball, Cattermole gets sent off hopefully we take the penalty and then it is 11 Stoke players against 10 Sunderland players with 20 minutes to go, Shawcross doesn't get sent off and it is a completely different game.
"I am not sure if it was over the line or not, I don't think he could give it or the linesman on the over the line, but what we are disappointed with is it hit his hand, rolled down it and then pushed it away.
"I have 800 games and I have not had a run like it in respect of the decisions.
"You go into games knowing they are going to make mistakes, but you just hope they don't make game-changing mistakes and again unfortunately this has happened.
"Last week with Tuncay at Everton, the week before Gary Neville two bookable challenges and didn't get sent off."
