Juventus fullback Daniel Alves has suffered a leg fracture in defeat at Genoa.
Alves was played in midfield for the day and was stretchered off following a collision before being taken to the local hospital for an X-Ray.
Juve released a statement confirming initial tests showed a fracture of the left fibula, which will be evaluated again tomorrow.
Globo Esporte in Brazil suggest he could be out for up to four months.
Giorgio Bonucci also was forced off with a trauma to the flexor muscle in the left thigh and this too will have more in-depth tests on Monday.
