Sheffield Wednesday manager Dave Jones insisted his side were denied a "stonewall" penalty at a crucial time in the 2-0 defeat to Blackpool.
The visitors were a goal up when Michail Antonio was upended the the box, but the Owls' penalty claims were given short shrift by referee Andy D'Urso.
"We had a stonewall penalty again which the referee said Antonio went down too easy," Jones said.
"But I think a pull is not going down too easy. I'm getting fed up now, the referee has to give that.
"He is clipped from behind and pulled by the arm and that is a clear penalty. One day someone is going to see it, but they just pat it off as 'he went down too easy'.
"That's poor on their part and probably one of the reasons why he has been demoted down. He is five yards away, one day someone is going to give us something."
