Alan Shearer blasted referee Howard Webb after he disallowed a goal from Mark Viduka as Newcastle plunged back into the relegation zone.
The Magpies were trailing 1-0 to Fulham at St James' Park when the Australia international headed home a 50th-minute Danny Guthrie corner. Referee Webb ruled out the strike for a foul on goalkeeper Mark Schwarzer by Kevin Nolan, although television replays suggested Shearer's side were desperately unfortunate.
Manager Shearer and assistant Iain Dowie confronted the official as he left the pitch, and the manager said: "We are bitterly disappointed at the disallowed goal. I have seen it and I can't see anything that's wrong with it."
He added: "Probably what has happened is the goal on Monday night from Steven Taylor has been highlighted that much this week that one or two people have thought, 'We might try to clamp down on that this weekend'.
"You are allowed to put someone in front of the goalkeeper - I am not aware that you are meant to get out of the way of him.
"I thought their player was blocking him more than Kevin Nolan was, so I am disappointed with that."
Asked if he had managed to speak to Webb, Shearer said: "Not yet, but I am going to try.
"I thought he got the big decision wrong today. When he looks at it, he might think that as well."
