Jefferson, 27, spent part of the 2017/18 season on a two-way contract with the Timberwolves after going undrafted out of Duke. He subsequently signed a two-way deal with the Magic for the ’18/19 season and then was promoted to Orlando’s standard roster at the start of the ’19/20 campaign before being waived in February.
Despite spending parts of three seasons on NBA rosters, Jefferson has seen limited playing time, averaging 1.4 PPG and 1.5 RPG in 30 total games (4.7 MPG). He has thrived at the G League level, however, recording 18.5 PPG, 12.2 RPG, and 2.9 APG in 88 NBAGL contests (34.2 MPG) for the Iowa Wolves and Lakeland Magic.
Jefferson was with the Celtics during the preseason after signing an Exhibit 10 contract, but was waived 10 days ago when the club set its regular season roster. He’ll look to help jump-start a Galatasaray squad that is off to a slow start this season, with a 5-9 record in Turkish League play.
