 In July 2014, Pressey re-joined the Celtics for the 2014 NBA Summer League. His performance earned him a roster spot for the regular season, as the team guaranteed his contract for the 2014 – 15 season. On February 5, 2015, he was assigned to the Maine Red Claws of the NBA Development League. He was recalled the next day. On July 15, Pressey was waived by the Celtics.
