Maten played for the Heat on a two-way contract last season, splitting time between Miami and the Sioux Falls Skyforce. The 23-year-old forward averaged an impressive 23.5 PPG and 9.7 RPG in 30 G League contests, earning a spot on the All-NBAGL Second Team. Hoever, he was waived by the Heat in July.
The Celtics already have filled both of their two-way contract slots (Tremont Waters, Max Strus). Once Boston officially signs Maten and finalizes its reported deal with Kaiser Gates, the team’s training camp roster will feature 20 players, which is the maximum allowed.
