Juventus have confirmed that defender Martin Caceres has suffered a muscular problem.
The 27-year-old was forced to come off in the first half of yesterday's 1-0 win over AC Milan.
"Martin Caceres left the action during the first-half of yesterday evening's 1-0 triumph over Milan due to a muscular problem in his left thigh," said a statement on the club's official website.
Caceres joined Juventus permanently in May 2012, after two previous loan spells with the club.
