Bayern Munich have suspended goalkeeper Oliver Kahn for one game and fined him €25,000 for a breach of club discipline.
Bayern said in a statement that Kahn, the club captain, would be sidelined for Saturday's Bundesliga clash away to Hertha Berlin 'for disciplinary reasons'.
The club gave no details as to why coach Ottmar Hitzfeld decided to take such action.
However, the 38-year-old criticised Bayern's new recruits Franck Ribery and Luca Toni, telling Kicker: 'The new players need to get used to our high expectations.
'It is not good enough to make a bright start. One or two (players) have got to work out that two or three good games are not enough.
'Bayern is not Marseille or Fiorentina; we are like Real, Man United, Barca or Milan.
'It is hard to get a team together because we always need three interpreters. There is no pleasure in our game anymore, and every player has got to ask themselves why.
'I don't have the precise answer, but every game is getting a bit worse.'
Bayern lead the Bundesliga by two points from Werder Bremen, with just Saturday's game to go before the long mid-season break.
