Nocioni is still recovering from a left ankle injury.
After an MRI exam on the ankle, the Sixers team doctor recommended that Nocioni stop all basketball and impact activity until the team opens training camp at the end of September.
Nocioni was acquired from Sacramento this summer as part of the trade that sent Samuel Dalembert to the Kings.
Nocioni was scheduled to play for Argentina.
