The 32-year-old joins Stuttgart's Alexander Nuebel and Hoffenheim's Oliver Baumann as the goalkeeping options in the 23-man roster.
Currently, Germany's first-choice goalkeeper, Marc-Andre Ter Stegen of Barcelona, remains sidelined due to a significant knee injury. Additionally, Borussia Dortmund midfielders Julian Brandt and Felix Nmecha have been reinstated to the squad.
Brandt has not represented Germany since November of the previous year, while Nmecha earned his sole international cap under former coach Hansi Flick in March 2023.
Germany is set to host Bosnia and Herzegovina in Freiburg on November 16, followed by an away match against Hungary in Budapest three days later. The team has already secured a place in the Nations League quarter-finals, achieving three victories and one draw in the current campaign.
"Having reached the quarter-finals early, our goal is to win our Nations League group, ideally in front of our supporters during the home match in Freiburg," Nagelsmann stated on Thursday.
In addition to Ter Stegen, Nagelsmann is contending with several injury absences. West Ham forward Niclas Fuellkrug, Stuttgart's Jamie Leweling, Bayern midfielder Aleksander Pavlovic, winger Leroy Sane, Borussia Dortmund defender Waldemar Anton, and RB Leipzig's David Raum are all unavailable.
“We have a strong squad, even if we have to restructure in some positions due to injuries,” added Nagelsmann.
“Leroy Sane needs more match practice and rhythm after his break. Felix Nmecha has stabilized at BVB and, like Julian Brandt, is back after recent good performances.”
According to reports from German media on Thursday, 18-year-old midfielder Paul Wanner declined a call-up for the upcoming matches, opting to remain with the under-21 team.
Wanner, currently on loan at Heidenheim from Bayern Munich, is eligible to represent both Austria and Germany but has yet to decide on his senior international allegiance.
