Following a 1-0 win over Torino, Stefano Pioli’s men are getting ready to face Mourinho’s Roma at the Olimpico on Sunday.
The Rossoneri will have to deal with the absences of Alessandro Florenzi, Mike Maignan, Messias and Castillejo.
According to Sky Sport, attacker Ante Rebic is also questionable for the big match.
The Croatian international underwent therapy and is at risk of missing out on Roma-Milan due to a persisting ankle injury.
