Andrea Pirlo will have to prove his fitness ahead of the Lazio game after he picked up a problem in Juventus training on Thursday.
According to Sky Sport Italia, the Italian international failed to complete today’s session because of a muscle complaint.
The summer signing from Milan will reportedly undergo tests on Friday to see how serious the issue is and whether he could feature on Saturday.
Juventus, joint Serie A leaders with Lazio, haven’t played without the 2006 World Cup winner yet this season.
Pirlo has started and completed all 10 of the Old Lady’s League matches under new boss Antonio Conte.
