Milan winger Samuel Chukwueze has undergone surgery in London after suffering a ruptured thigh tendon, the club have confirmed.
The Nigeria forward is expected to be out for about three months, according to reports in the Italian media.
Chukwueze has made eight appearances for Milan in all competitions this season, scoring twice. His injury leaves the club without one of their wide attacking options as they continue their domestic and European campaigns.
Ruben Amorim’s side have collected 21 points from their opening 10 Serie A matches and are fifth in the table.
Milan’s next fixture is against Hungarian club Ferencvarosi TC in the Europa League on 5 November.
