Jazz add Hayden Gray

Hayden Gray has agreed to a contract with Boston. He appeared in one game for Utah last season, scoring six points in nearly 25 minutes. Gray spent most of the year with the Maine Celtics, averaging 9.9 points, 2.8 rebounds and 5.8 assists across 48 G League games.

Boston enters training camp with 14 players on standard deals, including offseason additions Paul George, Mitchell Robinson, Mike Conley and rookie Chris Cenac Jr., according to CelticsBlog's Noa Dalzell. Amari Williams and Dillon Mitchell already hold two-way contracts, leaving one two-way spot open.

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.
