Jankovic, who tore his knee ligaments in September in an Italian Serie A match for his club Genoa, was named by Serbia coach Radomir Antic in a 23-man squad on Friday.
Antic, who steered Serbia to World Cup in South Africa for the first time as an independent nation, also called up uncapped goalkeeper Zeljko Brkic.
The Under-21 keeper has been widely tipped to make Serbia's World Cup squad after Vladimir Disljenkovic last week made himself unavailable for selection because of recurring injuries.
Serbia face Germany, Australia and Ghana in Group D while Algeria's Group C opponents are England, Slovenia and the United States.
Squad:
Goalkeepers: Vladimir Stojkovic (Wigan), Zeljko Brkic (Vojvodina Novi Sad)
Defenders: Branislav Jovanovic (Chelsea), Antonio Rukavina (Munich 1860), Nemanja Vidic (Manchester United), Neven Subotic (Borussia Dortmund), Aleksandar Lukovic (Udinese), Aleksandar Kolarov (Lazio), Ivica Dragutinovic (Sevilla)
Midfielders: Dejan Stankovic (Inter Milan), Nenad Milijas (Wolverhampton Wanderers), Gojko Kacar (Hertha Berlin), Zdravko Kuzmanovic (Vfb Stuttgart), Radosav Petrovic (Partizan Belgrade), Bosko Jankovic (Genoa), Milos Krasic (CSKA Moscow), Zoran Tosic (Cologne), Milos Ninkovic (Dynamo Kiev), Milan Jovanovic (Standard Liege)
