Ghana have thrown out former Portsmouth duo Kevin-Prince Boateng and Sulley Muntari from their World Cup camp.
Boateng hurled "vulgar verbal insults" at coach Kwasi Appiah, the Ghanian FA said, while teammate Sulley Muntari slapped Ghana Management Committee member Moses Armah Parker in an "unprovoked physical attack" during a separate meeting.
Muntari’s accreditation for the 2014 World Cup has been withdrawn with immediate effect, along with Boateng's.
"The Ghana Football Association (GFA) has approved coach Kwesi Appiah’s decision to suspend Kevin-Prince Boateng indefinitely from the Black Stars.
"The decision takes immediate effect.
"The decision was taken following Boateng’s vulgar verbal insults targeted at coach Kwesi Appiah during the team’s training session in Maceio this week.
"Boateng has since showed no remorse for his actions which has resulted in the decision.
"Boateng’s accreditation for the 2014 World Cup has been withdrawn with immediate effect."
Boateng told German tabloid Bild: "No one should think that I insulted the manager. I'm now leaving and wish my teammates best of luck for the game."
Boateng and Muntari have been integral members of the Ghanian side in recent years and both scored at the 2010 World Cup, when the country reached the quarter-finals for the first time in South Africa.
The duo's ejection is the worst possible preparation for the Black Stars' final World Cup group game against Portugal this afternoon. Victory for Ghana will take them through to the last 16, provided Germany beat the USA and there is a two-goal swing.
Muntari is suspended for the Portugal clash after picking up two yellow cards against the USA and Germany.
The latest farce comes after Ghana's players needed a phone call from their country's president to get them on the plane to Brasilia for the pivotal Portugal fixture.
Ghanaian players were placated over unpaid bonuses - between $1.7 million and $2.3m - when a specially chartered plane was flown over to Brazil since the players didn't trust officials would make the electronic transfers.
