The Ballon d’Or winner limped off in evident pain during last night’s 1-1 draw with Reggina at San Siro.

He was rushed to hospital for X-Rays after Coach Carlo Ancelotti admitted he was “worried,” but no fractions or lesions were found.

However, this morning more tests confirmed the diagnosis of a sprained left foot that will keep him out of action for “at least two weeks,” according to a note released by the official club website.

This means Kaka will miss out on Tuesday’s international friendly between Brazil and Italy, to be played in London’s Emirates Stadium.

He will above all be ruled out of next Sunday night’s Milan derby and most likely also the home Serie A game with Cagliari on February 22.

It is a bitter blow for the Rossoneri, but means Ronaldinho is now the favourite to start the derby.

Dinho has positive memories of this match, as he scored his debut Serie A goal against Inter earlier this season.
