The French team captain was injured Friday while scoring the only goal in France's victory before returning to his club.
France won 1-0 in Turkey in Zidane's first match as manager, but Kylian Mbappé, injured in the knee, will miss the next three games.
Zinedine Zidane was able to reunite all his players on Tuesday and is reportedly considering a return to a 4-3-3 system with Mbappé and Dembélé.
Zinedine Zidane led his very first training session at the head of Les Bleus as the new coach.
The former France number 10 will reveal the players selected for the four Nations League matches scheduled for late September and early October.
