The Artist Formely known as White Chocolate has called it quits, largely due to back pain. The Commercial Appeal reports: “Point guard Jason Williams announced his retirement Monday, ending his 12-year NBA career and a brief reunion with the Grizzlies this season. Williams, 35, signed with Memphis as a free agent on Feb. 7 but missed the team’s final 17 regular-season games with a sore lower back. In addition to two stints with the Griz, Williams played for the Sacramento Kings, Miami Heat and Orlando Magic. The 6-1 guard won the 2006 NBA Championship with Miami. Williams’ contract with the Griz included a player option for the 2011-12 season. He was last seen in FedExForum on March 30. He then left for Orlando to be with his family.”
