AC Milan medical chiefs baffled by Kaka injury
Kaka remains on the sidelines for AC Milan.
The former FIFA World Player of the Year has been suffering with a foot problem since February 7.
He again had to sit out as Milan beat Al Sadd 2-1 in Qatar in a friendly last night and he looks almost certain to miss out on playing Atalanta this weekend.
Milan medical chiefs have been unable to pencil in a date for the Brazilian's return to action.
