The Black Stars lost to Portugal on Thursday, 2-1, and both team saw their World Cup hopes dashed as Germany and the United States advanced in Group G qualifying.

However, they will be without Boateng and Muntari, with the Ghana Football Association (GFA) announcing on the morning of the game that Boateng has been suspended over claims he insulted Ghana coach Kwesi Appiah, while Muntari allegedly attacked a member of the organisation.

An official statement on Boateng said: "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 Boateng's accreditation for the 2014 World Cup has been withdrawn with immediate effect."

A separate statement on Muntari added: "The Ghana Football Association (GFA) has suspended Sulley Ali Muntari indefinitely from the Black Stars with immediate effect.

"The decision was taken in the wake of his unprovoked physical attack on an Executive Committee member of the GFA and a management member of the Black Stars, Mr Moses Armah on Tuesday June 24, 2014 during a meeting.

"Muntari's accreditation for the 2014 World Cup has been withdrawn with immediate effect."
