Schalke defender Christoph Metzelder has confirmed he will retire at the end of the season.
The 32-year-old former Germany international will hang up his boots after Saturday's trip to Freiburg.
"I am just being honest with myself and I feel that I am no longer physically able to play consistently at this level," he said.
"And after 13 years, the fire inside me, which is necessary for this job, has burnt out."
Germany coach Joachim Low has responded to the losses of Bastian Schweinsteiger to suspension and Julian Draxler to injury by calling up Marcell Jansen and Patrick Herrmann to his squad to face Kazakhstan on Tuesday.
Hamburg's Jansen, whose last international appearance came in September 2010, will provide cover to the defence - where captain Philipp Lahm may well be rested - while Herrmann could pick up his first cap.
The Borussia Monchengladbach midfielder will link up with the senior squad for the first time direct from Israel, where he has been in action for Germany's under-21s.
Germany boss Jogi Low has added Sven Bender to his squad for Tuesday's World Cup qualifier with Kazakhstan in Nurnberg.
The Dortmund midfielder will fill in for Bastian Schweinsteiger, who picked up a yellow card in the 3-0 win over Kazakhstan, earning a suspension.
Happy birthday to one of the greatest central midfielders the world has ever seen: German box-to-box beast Lothar Matthaus, who's 52 today. We salute you.
Eintracht Frankfurt's first-choice goalkeeper Kevin Trapp is set to miss the rest of the season after breaking his left hand while filming an advert.
Trapp tripped and fell during a publicity shoot for the Germany Under-21 team.
Scans have revealed the 22-year-old suffered a break that is set to jeopardise Eintracht's European ambitions.
Trapp offered his version of events to Bild: "I don't know what happened. I started walking and all of a sudden I was down on the ground."
