BRIGHTON -- Lonnie Walker IV's status with the Boston Celtics remains uncertain. He joined the team on a one-year Exhibit 10 contract, which allows flexibility for the Celtics to either keep him on the main roster or assign him to their G-League affiliate in Maine. Walker has impressed during training camp, but the Celtics are still working through their roster adjustments, with tough decisions looming regarding final spots. Head coach Joe Mazzulla has praised Walker’s effort, though it remains unclear if his solid camp showing will translate into a guaranteed role for the regular season. CLNS Media's Bobby Manning provides a Walker update after speaking to Joe Mazzulla at Friday's practice.
