Referee Andy D'Urso has no plans to include a report of Saturday's fiery penalty incident at Old Trafford, despite fearing he was going to be pushed over by Manchester United players.

A group led by skipper Roy Keane reacted furiously to a spot-kick awarded to Middlesbrough in the Premiership match.

Keane was booked as a crowd of United players, including eventual matchwinner David Beckham, forced D'Urso to retreat away rapidly.

"If I had stood my ground I would have been pushed over," D'Urso told The Mirror.

"The best thing for me to do was just keep backing off and backing off. I felt under pressure."

The official took no further action, and appears unlikely to do so in his report of the game.

"One or two of them were showing their displeasure while a couple were trying to restrain the ones giving me grief. They were obviously not pleased I'd given the penalty.

"I had no doubts it was a penalty. I was clear about that. I saw Stam nick the ball from Juninho but he took his legs at the same time."

Television replays confirmed that he had made the correct decision, while Mark Bosnich saved Juninho's kick.

The absence of anything in D'Urso's report leaves the video footage of the scenes which followed the decision as the only evidence the FA could act on.

United boss Sir Alex Ferguson tried to play down the incident afterwards, claiming his players were just upset because they did not feel it was a foul.

"They obviously didn't think it was a penalty kick," he said.

Boro manager Bryan Robson was also unhappy with D'Urso for sending off Christian Ziege.

Robson questioned Beckham's conduct in the two incidents which earned the German international two cautions and a red card.

He also believed Stam should have faced further censure for denying Juninho a goalscoring opportunity but was not even booked.

"I'm concerned that Christian Ziege got sent off for something that looked harsh - and Jaap Stam, if the ref thought it was a penalty should have sent him off," said the Boro boss.

"I asked that question after the game but the ref just blanked me."
