Ghana midfielders Sulley Muntari and Kevin-Prince Boateng have been suspended indefinitely from the national team and sent home from the World Cup for disciplinary reasons.

Ghana's two biggest stars were axed just hours before their crucial World Cup Group G match against Portugal on Thursday.

Milan's Muntari and Boateng of Schalke, who both had spells with Portsmouth as well as the latter at Tottenham, have both had their tournament accreditation withdrawn, according to the Ghana FA.

They will play no part as the Black Stars attempt to beat the Portuguese in Brasilia and qualify for the last 16.

Muntari was reported to have physically attacked Moses Armah, one of Ghana coach Kwesi Appiah's management team, while Boateng verbally insulted Appiah during a heated team meeting.

The Ghanaian squad had been in a state of rebellion over unpaid appearance with the country's government believed to have sent out in excess of US$3million (£1.8m) on a chartered plane to Brazil to pay the players in an attempt to appease the situation.

A statement from the association said: "The GFA has suspended Sulley Ali Muntari indefinitely from the Black Stars with immediate effect.
