QPR boss Mark Hughes and several players were involved in an ugly altercation with fans after Saturday's 2-1 defeat at Bolton.
Hughes was the target of a torrent of foul-mouthed abuse at Euston railway station from a group of Rangers fans who had returned to the capital on the same train.
One fan then 'squared up' to defender Clint Hill and forward Jamie Mackie after they intervened.
Djibril Cisse acted as peace-maker and led Hughes and the players to an awaiting team coach.
The fracas happened hours after QPR had dropped into the bottom three in the Barclays Premier League following the defeat at fellow-strugglers Bolton.
One Rangers fan, who was travelling with his six-year-old son, told westlondonsport website: 'It was horrible to witness.
'I’d say it was three to five people who were really having a go at them and one guy in particular who was squaring up to Jamie Mackie and Clint Hill and clearly looking for a fight.
'None of the players reacted as far as I could see. I saw Djibril Cisse trying to calm people down and then someone leading the players away.
'They made their way to a coach that was waiting for them and a much bigger group of fans gathered around the coach to basically applaud the team and show their support.'
A club spokesman played down the incident, saying: 'Some fans were having a go at Mark Hughes and Jamie stood up for the manager.
'It was a case of him saying ‘Come on guys, we’re all in this together’ rather than anything else. It wasn’t anything serious.'
