Detroit didn't re-sign Stanley after his second 10-day contract expired Tuesday, Keith Smith of Spotrac.com reports.
Stanley is expected to remain in the organization as a member of the G League's Motor City Cruise. Over the course of his two 10-day pacts with the Pistons, Stanley appeared in seven games and averaged 6.9 points, 2.4 rebounds and 0.6 assists in 20.3 minutes.
