Sevilla have confirmed that they will be without Marko Marin for up to a month, after tests confirmed the extent of a hamstring injury.
The on-loan Chelsea man retired from training early on Monday with discomfort felt in his left thigh and tests have since confirmed the worst.
The German is set for between three and four weeks on the sidelines now, with it revealed that he has suffered a strain in his hamstring between grade I and II in severity.
