Juventus have confirmed key midfielder Arturo Vidal limped out of the 3-0 win over Napoli with a muscle problem.
The Chilean was replaced in the 86th minute of the Juventus Stadium tie by Italian international Claudio Marchisio.
The club have noted that the former Bayer Leverkusen man reported discomfort in the adductor muscle of his right thigh.
Vidal will undergo a series of tests over the next few days to assess the extent of the problem.
Juventus will next be in action in two weeks’ time at Livorno once Serie A resumes after the international break.
Vidal has scored seven goals in 16 games for the Old Lady so far this season.
