Ivory Coast say Chelsea ace Didier Drogba is still suffering from malaria.

Drogba was declared fit by his club last week and played in the defeat to Sunderland on Sunday.

But he turned up for international duty and immediately ruled out of the friendly in Poland.

"The player underwent tests that revealed the persistence of malaria," read a statement from the Africans on their official website. "Didier Drogba has been declared unfit to take part in the friendly match against Poland."
