The striker - who has scored six goals in eight appearances for his country - was taken off after 32 minutes of RB Leipzig's 2-0 UEFA Champions League defeat to Besiktas last Wednesday (AEDT), afterwards admitting that the raucous atmosphere at the Vodafone Park had made him dizzy.

Leipzig said in the aftermath of its trip to Istanbul that there was "no exact diagnosis" to the problem, but Werner did not feature in his club's 2-1 victory over Bundesliga rival Cologne at the weekend.

Now the 21-year-old will also sit out Germany's final two games in Group C, as it travels to Northern Ireland on Friday before hosting Azerbaijan in Kaiserslautern on 9 October.

National coach Joachim Low opted not to call up a replacement at short notice, meaning a squad of 22 will make the trip to Belfast.

The world champion will be without Mesut Ozil and Sami Khedira, as well as long-term absentees Manuel Neuer, Jonas Hector and Mario Gomez, as they look to secure a place at Russia 2018.
