Germany midfielder out of Confederations Cup

Germany youngster Diego Demme won't play against the Caltex Socceroos at the Confederations Cup after he was ruled out due to injury.

The RB Leipzig midfielder has been ruled out of Germany's Confederations Cup campaign with a back injury.

The 25-year-old, who made his debut as a substitute during Germany's 7-0 World Cup qualifying win over San Marino on Saturday, will remain with Germany's squad until Thursday to receive treatment.

In a statement on their official website, the German Football Association (DFB) confirmed boss Joachim Low will not call up a replacement for Demme ahead of the tournament in Russia.

The world champions face Australia in their tournament opener in Sochi on Tuesday (AEST).
