Kenyon Martin agreed to a contract buyout, can't return to the NBA

Adrian Wojnarowski: Kenyon Martin has agreed to a contract buyout with Xinjiang of the China Basketball Association, sources tell Y! Sports. As part of agreement, Martin must honor China Basketball Association rules, wait until end of team's season for return to NBA, sources said. Xinjiang plays regular season through mid-Feb., and likely will make playoffs. Martin can't get letter of clearance for NBA until it's over. Martin is an unrestricted free agent and can sign anywhere in the NBA come the end of Xinjiang's CBA season. Martin's buyout will set the precedent for JR Smith, Wilson Chandler, Aaron Brooks in China: None will play in NBA until CBA season is over
