Chile midfielder Mauricio Isla's season could be over after he was diagnosed with a cruciate knee ligament injury on Sunday.
The Udinese player had to be stretchered off after a clash with AC Milan's Massimo Ambrosini on Saturday.
His club said they will need several more days to fully assess the extent of his injury but a ruptured cruciate injury ususally requires a period of around six months on the sidelines.
