Already without the suspended Lucio, Inter may be unable to call on Cristian Chivu for this weekend's Milan derby.
The Romanian international has picked up a right calf problem which looks serious enough for him to miss out on the San Siro showdown.
The former Roma player will undergo more tests on Tuesday but it seems as if boss Leonardo will have to invent something in defence.
The Brazilian tactician already has his fingers crossed that Andrea Ranocchia will be fit in time for the game.
Ranocchia pulled out of the Italy squad last week with a knee problem, but he's optimistic that he will recover in time.
