Ozil, who missed their 1-0 friendly win over England on Wednesday, skipped Friday's training session before the team headed for Baku and will have to wait until later on Saturday for a final decision, the coach said.
"Yesterday Sami Khedira, Mario Gomez and Julian Draxler trained normally with no problems at all," Loew told reporters in Baku. The three players were also sidelined for the England game.
"Everyone trained apart from Mesut," Loew said. "He will have to wait until the last training (session). He had back problems and received treatment yesterday and today. We will train today and then decide."
Loew said he was planning to start with Benedikt Hoewedes as a partner to Mats Hummels in the central defence, replacing Antonio Ruediger, who had started against England.
