Left knee arthroscopic surgery for Simon Kjaer following his injury during the match against Genoa.
The player suffered ligament damage and is expected to be away from the pitch for a long time.
Milan made it known.
Kjaer underwent an MRI and a specialist evaluation this morning which confirmed the need for surgery.
The Rossoneri defender was injured in the 4 'of the first half of last night's match against Genoa in Marassi and was forced to leave the pitch on a stretcher.
It is an important loss for Milan's defensive balance.
On Sunday against Salernitata, however, Pioli can count on Romagnoli who, once the disqualification day is served, will be called again.
