Sulley Muntari and Kevin-Prince Boateng have been expelled from Ghana's World Cup squad for disciplinary problems.
The Ghana Football Association said both had been "suspended indefinitely" in a statement.
AC Milan midfielder Muntari has been punished for an alleged "unprovoked physical attack" on a member of management staff.
Boateng was sent home for "vulgar verbal assaults" towards coach Kewsi Appiah during a training session, for which he had shown "no remorse".
The announcement comes just hours before Ghana play Portugal in their crucial final game in Group G.

In a YouTube video posted by the official US Soccer account, the Anchorman star is brought on stage to a hero's welcome at a gathering of fans in the city of Recife.
Although he admits he is not in "soccer shape" at the moment, Ferrell promises the fans he will do his utmost for Jurgen Klinsmann's team.

The US football team has provided an excuse letter for excited fans who want to avoid work to watch their clash with Germany.
Signed by Jurgen Kinsmann, the letter says: "I understand that this absence may reduce the productivity of your workplace, but I can assure you that it is for an important cause."
Both sides are on four points in Group D, and a draw will put them through to the last 16 ahead of Ghana and Portugal.
