The Spurs waived Payne on Monday, Adrian Wojnarowski of ESPN reports.
Had he stuck around in San Antonio, Payne may have had a chance to open the season as Tre Jones' top backup, but the franchise is going in a new direction and has several young candidates to fill the role, including Malaki Branham and Blake Wesley. Payne will presumably seek to join a contending team as he heads to the open market.
