The Ghana Football Association (GFA) has approved the decision of the head coach of the Black Stars Kwesi Appiah to suspend two senior players indefinitely from the national team.

Sulley Ali Muntari and Kevin-Prince Boateng were axed from the team camp following varied degrees of misconduct.

The decision takes immediate effect, the GFA said in a statement received here on Thursday.

"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," the GFA said.

It said Boateng has since showed no remorse for his actions which has resulted in the decision.

Sulley was suspended in the wake of his unprovoked physical attack on an executive committee member of the GFA and a management member of the Black Stars, Moses Armah last Tuesday during a meeting.

The two players' accreditation for the 2014 world cup has been withdrawn with immediately.

The decision comes a few hours into Ghana's final group G game against Portugal later on Thursday.

Ghana needs to beat Portugal to stand any chance of leaving Group G alive.
