Grill waived by Boston, headed for the Maine Celtics

Boston has signed free agent guard Caleb Grill to a training camp contract, according to Paul Garcia of The Spot Up Shot. The deal is expected to carry Exhibit 10 language, letting Grill earn a bonus worth up to $91K if waived and he spends 60 days with the Maine Celtics.

Boston's G League affiliate acquired the returning player rights to center Ibou Badji, forward Tyler Polley and guard Erik Reynolds II from the Windy City Bulls.

Nikola Vucevic has signed back with the Orlando Magic on a one-year, $3.9 million minimum contract, ending a nearly five-year absence.
