The unsavoury incident happened just 24 hours after the attacks and included stripping, swearing and vomiting at the hotel near Heathrow airport, which was full with Americans stranded by flight cancellations, according to the News of the World.
The group included Frank Lampard, Jody Morris, John Terry, Eidur Gudjohnsen and former Chelsea defender Frank Sinclair.
The group went on the binge after Chelsea's game that night against Bulgarian outfit Levski Sofia had just been called off as a mark of respect for victims of the attacks
Antonio Parisini, a manager at Heathrow's Posthouse hotel, said: "They were causing lots of noise and knocking things over in the bar and upsetting everyone. They were really drunk."
Chelsea managing director Colin Hutchinson condemned the players' behaviour as "totally out of order" and said they had each been fined two weeks' wages by the club with the money being donated to the fund helping families of the victims of the America disaster.
Hutchinson also insisted that none of the four Chelsea players had intended to insult or abuse any member of the public, least of all Americans affected who were still coming to terms with the terrible tradegy.
"The players concerned have each been fined two weeks' wages and that money is being donated to the American appeal," said Hutchinson.
"Obviously we are condemning their behaviour by fining them. We have acted very quickly in this matter as we were only told about it last night (Saturday).
"Claudio Ranieri and myself met the players first thing this morning. Normally we would not tackle disciplinary matters on the day before an important game against Middlesbrough.
"However, because of the seriousness of the matter, we have done it today. In the meeting with the players, we reminded them again of their responsibilities.
"They were categorical that in no way had they intended to insult any individuals and they said that they certainly didn't abuse anyone.
"They were loud between themselves but they, like everyone at the club, have been as hurt and moved by what has happened in the United States as anyone else.
"Their behaviour was totally out of order but there is no way that the players went out, in any shape or form, to insult or abuse anyone.''
