The 22-year-old was not selected for the friendly against Wales and the World Cup qualifier away at Latvia.
However, it is understood that Bellingham actually requested to be left out of the squad rather than being dropped by Tuchel.
This decision was made due to Bellingham still experiencing some discomfort from his recent injury, which he had only just returned from.
He felt it was best to take more time to work on his recovery and return to full fitness.
