The goal was to avoid injuries during the international break, but Bayern Munich were bitten by the injury bug in the first international match. During Germany's loss to the Republic of Ireland, Mario Götze was removed from the match in the first half due to an injury.
Bayern haven't announced anything on Götze's injury and probably won't until more information is available. However, the DFB revealed in their match report that Götze suffered an adductor injury. Kicker and Abendzeitung are also reporting the same injury, kicker suggesting it was on the left side of is adductor.
Germany manager Joachim Löw confirmed after the match that Götze would miss the upcoming match on Sunday against Georgia. Kicker proceeds to speculate that it's possible for Götze to miss matches for Bayern, also. Until he gets back to Munich, it won't be known exactly how much time they expect him to miss.
With the loss to the Republic of Ireland, the match against Georgia holds ultra importance for Germany. If results go against them on Sunday, they could lose one of the two automatic qualifiers to the tournament next summer in France. For the current world champions, this would be immensely embarrassing.
