The Boston Celtics assigned 2015 top pick Terry Rozier to the Maine Red Claws of the NBA Development League Saturday. He’ll join fellow Celtics teammates James Young and Jordan Mickey for Maine’s game against the Canton Charge. Rozier, the No. 16 pick in June’s draft, has logged 44 minutes in five appearances for Boston. He’s in line for extended game reps after a DNP on Friday against the Hawks.
