The Republic of Ireland's senior players told James McClean his foul-mouthed Twitter rant was out of order, Kevin Doyle has revealed.
McClean was furious at watching the Republic struggle to a 2-1 win over Kazakhstan from the bench last Friday evening.
The Sunderland winger, 23, described his personal experience in Astana as a "f*****' joke" on Twitter, and added that he was left "embarrassed" at not coming on to the field of play during the game.
McClean was expected to start Tuesday night's friendly against Oman at Craven Cottage but he will now once again start on the bench, even though he apologised for the rant and was given a dressing down in front of the squad.
Doyle, who came off the bench to score the winner in his 51st international appearance, spoke about how a group of senior members within the squad pulled McClean aside straight after the game to tell him he had crossed the line with his tweet.
He said: "We found out about it pretty much straight away and we said it to him straight away - it's not acceptable," Doyle said.
The Wolves man has seen his fair share of off-the-field controversies with the Republic during his 51-cap international career and he thinks McClean will actually benefit from the experience of his telling off.
"We ended up joking about it the next day," the 28-year-old added. "It's been good because it has probably got him integrated in to the group a bit more because we have all been taking the p**s out of him.
"We were thinking of getting him to sing in front of the group again - that made him nervous enough. I think he nearly cried the first time he did it.
"A few of the lads find it quite traumatic when they stand up in front of us so it might have been good for him."
Trapattoni has confirmed that only one player who started in Astana - James McCarthy - will begin Tuesday night's game, meaning the likes of Seamus Coleman, Shane Long and David Forde will have a chance to stake a claim for a regular place in the team ahead of next month's World Cup qualifier against Germany.
David Meyler and Robbie Brady will both make their debuts and Doyle will skipper the team, Trapattoni confirmed.
Meyler, 23, has missed a large chunk of the last two seasons through cruciate knee ligament injuries, but Doyle thinks the midfielder will have a long and successful international career.
"He hasn't looked out of place at all since he came in," Doyle said.
"I hope he does well tomorrow because he has been impressive in training and he has told me about his two cruciates on the same knee.
"I have never had a serious injury like that so I can't imagine what it's like mentally, never mind physically, to come back from that.
"That he has come back shows his character, what he is all about, and shows he will have no problem in dealing with what comes his way in the Ireland team."
Brady has not started a game for Manchester United yet but impressed during a loan spell at Hull last term and last week became the record goal scorer for the Under-21's.
Trapattoni sang the winger's praises yesterday and Doyle was similarly optimistic about the 20-year-old's chances of making a big impact in the full team.
"He is a star of the future," Doyle added.
"He is top scorer with Under-21's and he has settled in well. There has been no shyness or sitting back. He has slotted straight in."
Unlike England's game against Ukraine at Wembley, tickets have sold poorly for the Republic's game, with as little as 7,000 people expected to attend the clash in south-west London.
