Lonnie Walker IV was waived by the Boston Celtics after an impressive training camp, despite his efforts to secure a spot on the roster. The Celtics opted for financial flexibility, weighing the luxury tax implications of carrying an additional player.

Walker showcased his skills during the preseason, particularly after returning from Abu Dhabi, but ultimately, the team decided to prioritize roster management. He may still join the Maine Celtics and could be considered by other NBA teams facing injuries.
