AC Milan playmaker Kaka will miss next weekend's derby against Inter Milan after tests confirmed a foot injury.
Kaka, who scored Milan's goal from the spot in a 1-1 draw against Reggina on Saturday night, was forced to come off 12 minutes from time.
The club confirmed on Sunday that the Brazil international will be sidelined for at least a fortnight.
"AC Milan communicates that the footballer Kaka underwent medical tests today which confirmed a sprain to his left foot, ruling out a more serious injury," read a club statement.
"The prognosis is that he will be out for at least a fortnight."
As well as next weekend's derby, Kaka will miss Tuesday's friendly international against Italy and in all likelihood the match against Cagliari on February 22.
