The Memphis Grizzlies will not pick up the fourth-year option of Josh Jackson.
Jackson was acquired by the Grizzlies from the Phoenix Suns this offseason.
Jackson is playing for the Grizzlies' G League affiliate as he tries to work his way back to the NBA. Jackson has had a number of off-the-court issues.
Memphis will have the space to re-sign Jackson should they try to keep him next summer.
