Argentine Biglia's World Cup in doubt after back injury

The 32-year-old was forced off the pitch after 72 minutes in Milan's shock defeat to 10-man Benevento and the club confirmed Biglia has fractured two vertebrae in his back.

"AC Milan inform that Lucas Biglia reported a severe lumbar trauma due to an injury during Saturday's match against Benevento," the club said in a statement.

"The player has undergone medical examinations that highlighted a fracture of the transverse processes of the first two lumbar vertebrae. A detailed prognosis will be issued in the coming days upon completion of all medical tests."

The former Anderlecht midfielder moved to the San Siro this season on a 17-million-euro deal after four years with Serie A rivals Lazio.
