Blackburn boss Mark Hughes has launched a furious tirade on Bolton striker El-Hadji Diouf, accusing him of diving and elbowing Andy Todd in the face.
Diouf won a penalty for appearing to dive and Hughes said: "It was a diabolical decision. He has a reputation for diving and enhanced it.
"We were aggrieved because he threw an elbow at Andy Todd and the ref must've seen something because he booked him.
"He should have been sent off twice, once for that and once for simulation."
Hughes also admitted he was unhappy with referee Steve Bennet, claiming the official cost his side a point.
He added: "We have lost a point to a very poor refereeing decision. I blame them both, the referee and the player.
"They say refs need to do their homework and know the players they are going to come into contact with.
"I thought he would have done his homework. You have to look at previous.
"I think it is a problem that is getting worse and after the event you can take disciplinary measures but you can't change the result of this game.
"The referee was in exactly the right position to make the decision but he didn't. At the end of the day the lad dived."
