Jose Mourinho refused to speak to the media after he was sent to the stands during Chelsea's 2-1 defeat at West Ham.
The Blues' dreadful season hit a new low as they imploded at Upton Park with midfielder Nemanja Matic, first-team coach Silvino Louro and then Mourinho himself all dismissed.
Earlier this month, Mourinho was fined £50,000 and given a suspended stadium ban for criticising referee Robert Madley following their loss to Southampton on Oct. 3.
And the embattled Blues boss dodged the usual postmatch news conference after his side slumped to their fifth defeat in 10 matches.
On Friday, Mourinho said his relationship with the media would change after phone camera footage of him walking around in West London was published.
Chelsea's poor afternoon began in the 44th minute when Matic, already on a yellow card after fouling Mauro Zarate, cynically brought down Diafra Sakho to earn his marching orders.
The Blues players surrounded referee Jonathan Moss in protest with the official eventually booking Fabregas and Diego Costa.
Mourinho stood impassively on the touchline but, behind him, the incensed Louro's histrionics saw him removed from the dugout.
Only when the Portuguese failed to retake his position pitchside, instead appearing in the stand amidst a flurry of camera phones did word filter out that he too had been sent off.
Mourinho already has a suspended stadium ban hanging over him for previous indiscretions this season and is now likely to find himself in hot water with the Football Association once more.
Defender Gary Cahill told BBC Sport: "[The mood in the dressing room] is not great -- like you'd imagine when you lose games. Last season we weren't used to it. The lads are devastated.
"You're left scratching your head sometimes. In the first half a Cesc Fabregas goal could have been given and we had a goal that was nearly over the line. That sums up the way we're going.
"And then we've got the sending-off. Originally we played on -- we thought the referee had played on. Maybe the assistant called it back, I'm not sure sure what's happened there. We've not had the rub of the green, but we're not feeling sorry for ourselves. We have to work hard to turn this round.
"Not many words are being said at the moment. I'm sure we'll reflect in next day or so. We worked really hard with 10 men and had the majority of the play in the second half. It's a summary of our season at the minute."
Hammers manager Slaven Bilic said he had not spoken to Mourinho since the final whistle.
"I feel for him," the Croatian said. "Decisions from his point of view have gone against him. I would moan if it was against us. But they are not mistakes, they are matters of opinion.
"You can talk about those things. The sending-off I didn't see. The first one was definitely yellow, the second one was very far from me, but it looked like Sakho was already gone.
"But I think second yellows, especially in the first half, should be 'real' bookings. The disallowed goal? No one can say onside or offside even when you freeze the picture.
"But I'm very proud of my team and my club, it's brilliant to win against the champions."
Already trailing to Zarate's 17th-minute strike, Chelsea managed to haul themselves level in the 56th minute after Kurt Zouma and Gary Cahill challenged for Willian's corner, the ball falling kindly for the latter to thrash home.
However, West Ham substitute Andy Carroll had the final say, emerging from the bench to powerfully head in Aaron Cresswell's cross with 10 minutes left to inflict another defeat on Chelsea.
