Bertrand reacted angrily on Twitter to being accused of withdrawing from the England squad with a sore throat, and although Hodgson was quick to acknowledge the commitment of Bertrand to his country, he admits that the Chelsea full-back's language was unacceptable.
Hodgson told reporters: "I think his sentiments were laudable by telling people how much that he wants to play for England and that he was a little bit irritated that people suggested that he didn't want to play because he had a sore throat.
"But his choice of words were wrong. I am pleased to see that he has apologised for it and it is a reminder of how unbelievably careful that players of this profile have to be."
Hodgson had only called up Bertrand to the squad as a replacement for the injured Kieran Gibbs.
