Almost exactly seven days after Ashley Cole earned a Football Association misconduct charge for using the hashtag "#BUNCHOFT**S" when reacting angrily to a regulatory commission's written reasons for John Terry's ban for racially abusing Anton Ferdinand, Bertrand has come under scrutiny himself.
Bertrand was withdrawn from the squad to face San Marino due to illness, though he took offence at suggestions that a sore throat was behind the decision to leave him out of the game at Wembley.
He tweeted: "Just to clarify.... Its not a 'sore throat' Im ill.swollen glands in my neck... And constant headache for 3 days now and freezin cold
"Do you think a 'sorethroat' could stop me being apart of a match for my club or country? #yourf*****gnuts this is what every boy dreams of"
Bertrand's comments came just a day after FA chairman David Bernstein said England players would have to follow a new code of conduct - including guidance over the use of Twitter.
He quickly deleted the offensive tweet and apologised for his language, writing: "sorry if i offended anyone by swearing as i don't encourage that type of language.
"was just disappointed at the thought of people thinking i only have a sore throat.. which is not the case..."
Though manager Roy Hodgson said Bertrand would not face disciplinary action for his tweet, he did say the defender's comments were inadvisable.
"I think his sentiments were laudable - telling you how much he wanted to play for England and being a little bit irritated that someone suggested he doesn't play when he gets a sore throat - but his choice of words was wrong," Hodgson said.
"I am pleased to see he has apologised for it and as you rightly say, it reminds us how unbelievably careful the players have to be.
"It's not really a question from the FA's point of view that he will be charged; as you rightly say it is a lesson that needs to be learned and it is a lesson that we can all learn from."
Wayne Rooney, who will captain England against San Marino, said: "We know we have got responsibilities, whether that be on social networking sites or in general life and we have to try and live up to those expectations as best we can.
"I think obviously this week there has been isolated occasions but we are well aware of how we need to conduct ourselves and I am sure we will all do that well."
