AC Milan face losing Nigel de Jong after he snapped his Achilles tendon in victory over Torino.
Milan coach Massimiliano Allegri fears De Jong's season is over.
De Jong's injury will force Milan back on the market.
"We'll see what to do about De Jong's role in January, but we do have Sulley Muntari, Massimo Ambrosini and Mathieu Flamini," said Allegri.
