Bobic's eight goals in eight Bundesliga appearances for Hannover this season had made him the centre of much speculation before Voller announced his original 20-man squad last week.
The former Stuttgart and Dortmund target man last played for his country in February 1998 and will now replace Carsten Jancker, who suffered a rib injury playing for Udinese in Serie A at the weekend.
With first-choice striker Miroslav Klose struggling to shake off an ankle injury, it could well be that Bobic will make the starting line-up against the Oranjes in Gelsenkirchen.
21-year-old defensive midfielder Balitsch will replace his Bayer Leverkusen club colleague Carsten Ramelow, who is suffering from a stomach illness, in the squad.
