Andrea Barzagli suffered a suspected calf strain in training and Juventus could lose him for a month.
The defender reportedly pulled out during a warm-up ahead of their 3-0 Coppa Italia semi-final victory over Fiorentina.
According to Sky Sport Italia and Sport Mediaset, medics fear a calf strain.
Barzagli had been playing regularly after eight months out of action due to an on-going Achilles tendon problem.
If a calf strain is confirmed, it would mean Barzagli missing the Champions League quarter-final against Monaco.
