City's injury concerns are mounting ahead of a crucial period that includes the first derby of the season against neighbours and Premier League title rivals Manchester United.
David Silva and Aleksandar Kolarov are both likely to miss that game on Sunday week as well as Saturday's home game with Bournemouth.
Striker Sergio Aguero, last season's leading Premier League scorer, was also injured on international duty, while fullback Gael Clichy and midfielder Fabian Delph are also all currently missing.
Kompany did come through nearly an hour of Belgium's Euro 2016 tie against Israel on Tuesday, and is in the squad for Saturday, as well as Yaya Toure and Samir Nasri.
