The Thunder announced on Monday the signing of veteran guard Reggie Williams and the team waived training camp invitee Alex Caruso.
Both Williams and Caruso are likely to play for the Oklahoma City Blue of the NBA Development League this season.
Williams (6-foot-6, 205 pounds) has six seasons of NBA experience, including a three-game stint with the Thunder during the 2013-14 season. Williams played last season in Russia with Avtodor Saratov.
Caruso, a 6-5, 183-pound guard out of Texas A&M, did not appear in the Thunder's first five games of the preseason.
