Zhang got injured in the fitness test before this season started. He fell while squatting and injured his lower back. After being sent to the hospital, he was diagnosed with an acute contusion, which caused the recurrence of his previous injury.

In early January, Shanghai Sharks officially announced that Zhang had recovered from his injuries and returned to training with the team. During the all-star weekend, the CBA board of directors discussed Zhang's fitness test, with a result that eight clubs rejected the proposal to exempt the test or replace squatting with other items.
