General Manager John Hammond announced the signing Friday.
The six-foot-eight, 225 pound Wright has been with the D-League's Maine Red Claws for the last two seasons.
He played 38 games with the Red Claws this season, averaging 19.5 points and 8.1 rebounds per game. He's had 16 double-doubles this year, including six in his last eight outings.
Hammond was undrafted in 2011 and was selected by the Red Claws. He played in four games, then signed with the Golden State Warriors, appearing in 24 games that season. He earned a start in Golden State's season finale at San Antonio, and tallied a career-best 25 points and eight rebounds while shooting 11-of-14 from the field.
