Bolton boss Sam Allardyce says he should not have let his side play at Fulham as he was not told about referee Graham Poll using a listening device.
Allardyce is furious he only found out just before kick off that there would be a trial run for the link-up which lets refs talk to their assistants.
"I should've refused to play. He would have had to take it off," he said. "I am really sick I didn't do anything.
"You cannot introduce something without prior knowledge."
Allardyce added: "We had no communication regarding as to why and for what reason and what our responsibilites would be."
Poll went on to send off El-Hadji Diouf and book six Bolton players and Allardyce is convinced Poll handled the game differently because of the new technology.
"I had no time to prepare the players for the situation and clearly Graham Poll has had no time either," he told the club's in-house TV station.
"His performance - he was over-zealous - infuriated both parties and caused a lot of uneccesary indiscipline.
"He booked four of my players for dissent, which is quite amazing. It looks like my team are indisciplined and that me as a manager doesn't discipline his side correctly.
"Incidents in the game were caused by the referee being wired up. would still have complained though had there not been any incidents."
Referees' chief Keith Hackett admitted Allardyce should have been informed. He told the Daily Telegraph "I would like to have advised Sam a week in advance. But he should have no fear.
"What is said between player and referee is between player and referee.
"It's not communicated or saved on a disc to be used as further evidence, if you like, which I suppose might be his fear.
"We were going to use it at Manchester United versus Chelsea but in fact we had to cancel that."
