As a result, Fullkrug will be out of action for several weeks, which may impact his availability for upcoming matches.
Nagelsmann was initially planning to call up Fullkrug as an injury replacement for Stuttgart striker Jamie Leweling, who was unavailable due to adductor problems.
However, West Ham informed Nagelsmann of Fullkrug's injury before the team's match against Luxembourg, which may affect the striker's involvement in future games.
