Inter Milan midfielder Philippe Coutinho will be out of action for at least a month after suffering a stress fracture to his leg in the club's UEFA Europa League match on Thursday.

The Brazilian playmaker was withdrawn in the first half of I Nerazzurri's 1-0 victory over Partizan Belgrade, with medical tests confirming the extent of the injury.

A statement on the club's website said: "Following a collision with (Milos) Ostojic in the 30th minute of yesterday's encounter, Philippe Coutinho underwent tests which revealed a stress fracture to his tibia."

The 20-year-old, signed from Vasco da Gama in 2010, had been enjoying an extended run in the first team given the absence of injured Netherlands international Wesley Sneijder.
