There is a high risk that both Inter and Juventus will have to field their reserve goalkeepers in Saturday's Derby d'Italia.
Italian international Gigi Buffon was already unlikely to play for Juve after picking up a collarbone injury in training last week which has seen him miss the ties against Genoa and Fiorentina.
Now it seems that Julio Cesar may be absent for the Nerazzurri after the Brazilian failed to finish the match against Atalanta last night.
The Brazilian international was replaced during the interval at the Stadio Azzurri d'Italia after complaining of a thigh muscle problem.
The former Chievo man will undergo tests at some point on Thursday, but the Gazzetta dello Sport claims that he won't recover in time for this weekend.
Inter will thus field Luca Castellazzi, who saved a penalty in Bergamo, while the Bianconeri will respond with Marco Storari.
