The Boston Celtics have signed rookie forward Abdel Nader, and have waived guard Demetrius Jackson.

Nader, the reigning 2016-17 NBA G League Rookie of the Year, averaged a team-high 21.3 points (44.7% FG, 34.9% 3-PT, 79.4% FT), 6.2 rebounds, 3.9 assists, 1.00 steal, 0.83 blocked shots and 33.5 minutes over 40 games with the Maine Red Claws in his first professional season. The 23-year-old was originally selected by Boston in the second round (58th overall) of the 2016 NBA Draft.

Born in Alexandria, Egypt, Nader (6-6, 230 lbs.) became the first internationally-born player to be named Rookie of the Year in the G League. The 2016-17 G League All-Star scored at least 30 points in five contests, including a 32-point, 10-rebound, 8-assist game against the Long Island Nets on Jan. 6.
