Diaw has not played in the NBA since the 2016-17 season, which he spent with the Utah Jazz.
Diaw was selected No. 21 overall in the 2003 Draft by the Atlanta Hawks and spent his first two seasons with the team.
The Bobcats waived Diaw near the end of the 2012 season, and the Spurs brought him in to see if he could rediscover his game while playing alongside close friend and countryman Parker.
