The German is expected to be out of action for three to four weeks and could miss as many as four La Liga matches for Sevilla, as well as two Europa League fixtures
Sevilla's Marko Marin could face a month out of action after suffering a hamstring injury in training.
The on-loan Chelsea midfielder has undergone an MRI scan that revealed damage to his left hamstring, ruling the 24-year-old out for between three and four weeks.
It means that Marin could miss as many as four La Liga games, with Unai Emery's men 11th in the table and unbeaten in their last three league fixtures.
He is also likely to miss both Europa League ties against Slovan Liberec.
Marin has made 11 appearances for Sevilla since joining on loan from Chelsea in June, scoring twice.
Emery has been given some positive news, however, with Stephane Mbia able to train without pain ahead of an MRI scan to evaluate his recovery from a foot injury.
Kevin Gameiro (thigh) and Ivan Rakitic (groin) will continue to recieve therapy for their injuries.
