Steve Harmison says former England coach Duncan Fletcher will lose some friends for his criticism of Andrew Flintoff.
Fletcher's revelation that the Lancashire all-rounder arrived for training intoxicated before a One-Day International in Sydney hit the headlines on Monday.
The deposed tactician has also pointed to examples of poor leadership and unprofessional behaviour in his autobiography.
But as Flintoff embarks on yet another intensive rehabilitation period following a fourth operation on his left ankle, team-mate Harmison remains in his corner.
"There is an unwritten code in sport," Harmison told the Daily Mail. "What goes on in the dressing room stays in the dressing room.
"It was a code very dear to Duncan Fletcher's heart and, sadly, Duncan Fletcher has broken it.
"I'm not disputing that some of the things Andrew did were wrong. But if Fletcher had a big problem with Freddie's drinking in Australia, why on earth didn't he do something about it?
"He had the chance to act, so if he wasn't prepared to do something he clearly felt was right for the side because it might turn out to be unpopular, what was he doing in the job in the first place?"
Peter Moores took over at the England helm following the elimination at the World Cup in April, and Durham paceman Harmison feels Fletcher will find himself isolated even more from now on.
"Fletcher took me from a young player to someone who has won 50-odd Test caps," he added.
"And I admit I've given him a lot of problems to deal with. So it's disappointing that my relationship with him should end on such a sour note.
"Fred's pride will have been dented but no one in the England team will think any less of him because of what Fletcher has said.
"On the other hand, Fletcher might lose a few people he once called 'friend'."
