AC Milan boss Gennaro Gattuso will be without the services of defender Mateo Musacchio for up to two months.
It has been confirmed that Musacchio suffered a knee injury when he collided with team-mate Franck Kessie during the Rossoneri's 1-1 draw with Real Betis in the Europa League on Thursday.
It was initially thought that Musacchi had sustained a head injury as he appeared to be unconscious after the collision but a statement from AC Milan has indicated that the player may not play again this year because of a knee problem.
The statement revealed Musacchio "reported a trauma to his right knee that involved a lesion of the posterior cruciate ligament, an injury that will require six to eight weeks conservative treatment."
The Argentine defender joins fellow long-term injury victims Lucas Biglia and Mattia Caldara on the sidelines while Ivan Strinic is out indefinitely with a heart condition.
Giacomo Bonaventura and Gonzalo Higuain have also missed recent fixtures for a Milan team are currently fourth in Serie A.
Gattuso's team host table-topping Juventus on Sunday and are 4/1 to beat the Old Lady, who lost 2-1 at home to Manchester United in the Champions League on Wednesday.
AC Milan are 11/10 to finish in the top four in Serie A this term while Juve are 11/2 to win the Champions League outright.
