Jérémie Bréchet is facing a fortnight out after tests revealed the severity of the pulled calf muscle he suffered in FC Sochaux-Montbéliard's 2-1 defeat by Olympique Lyonnais on Tuesday.

The 28-year-old sustained the knock three minutes in to the Coupe de France loss and is certain to miss the weekend trip to Olympique de Marseille as Sochaux look to climb out of the Ligue 1 relegation zone.
