Ghana suffered a huge blow ahead of their FIFA World Cup™ play-off match with Egypt on Monday as Kevin-Prince Boateng was ruled out of the first leg on 15 October because of a left knee injury.

The 26-year-old - one of the stars of the Ghana side that reached the 2010 FIFA World Cup South Africa quarter-finals - suffered the injury in his club Schalke's 4-1 Bundesliga victory over Augsburg on Saturday.

Boateng only just agreed to return to the national side after staying away for two years, but he was unable also to play in their final World Cup group match against Zambia last month because of an injury he picked up in training for the game.

The winners of the play-off qualify for the finals in Brazil next year.
