Bologna defender Roger De Carvalho needs surgery after fracturing his jaw during a training ground exercise.
The Rossoblu were playing a game between ranks today when Carvalho accidentally collided with a teammate.
X-Rays showed he has fractured his jaw and will go under the knife to stabilise the injury over the next few days.
Gianluca Curci and Diego Perez have returned to full training after missing the last few matches.
