Inter midfielder Nicolo Barella has suffered a thigh injury and will miss at least the next two games for the Italian champions.
The 27-year-old Italy international, who has made 175 league appearances for Inter, has a strain in the rectus femoris of his right thigh, the club said in a statement.
His condition will be reassessed next week, the club added when announcing his injury on Tuesday.
Inter, sixth in the Serie A standings with eight points from five matches, visit Udinese on Saturday, before hosting Red Star Belgrade in the Champions League next Tuesday.
Simone Inzaghi s side will be desperate to recover Barella for their clash with surprise league leaders Torino on October 5.
Barella impressed as the Nerazzurri began their Champions League campaign with a goalless draw at Manchester City last week, creating two chances for team-mates and ranking first among all Inter players for possession regains (seven) and passes played in the final third (10).
