Nigel de Jong has snapped the Achilles tendon in his left leg and will be out for around five to six months, AC Milan have announced.
The former Manchester City midfielder, 28, came off injured midway through the first half of the Rossoneri's 4-2 win against Torino, immediately signalling to the bench that it was a serious problem.
A club statement on Sunday evening confirmed he had indeed suffered a complete rupture of the tendon and Massimiliano Allegri, speaking to MediaSet, dedicated the victory to the stricken Dutch international.
Allegri said: "The lads have dedicated the victory to Nigel, who unfortunately has suffered a ruptured Achilles tendon injury that will see him out for the season."
De Jong only joined the club in the summer in a move worth an initial £3.5m and, having already become a vital cog in Allegri's midfield, losing him for the rest of the season will be a huge blow for the San Siro outfit.
