Oklahoma City has placed veteran forward Donyell Marshall on waivers. Marshall, who is entering his 15th NBA season, was acquired from Cleveland in mid-February as part of the 11-player, three-team deal that sent Wally Szczerbiak and Delonte West from Seattle to Cleveland. Marshall played in only 15 games last season for the Seattle SuperSonics, averaging 3.8 points and 3.1 rebounds in 12.3 minutes per game. Marshall was likely to play less this season than he did a year ago following last week’s acquisition of veteran forwards Desmond Mason and Joe Smith. Marshall is in the final year of a contract that would have paid him $5.9 million. Oklahoma City must pay Marshall the remainder of his guaranteed salary, but the team has the option to negotiate a payment schedule to fulfill its obligations over a longer period of time. Marshall’s entire contract, however, will count against the team’s salary this season. Marshall will now be on waivers for 48 hours, allowing any team to claim him. If no team claims him he will clear waivers and can sign with any team at a negotiated salary. The move clears up a roster spot for Oklahoma City. NBA teams are allowed to enter the regular season with no more than 15 players on the roster. Including restricted free agent center Robert Swift, Oklahoma City will have 14 players under contract when Kyle Weaver and D.J. White sign their rookie contracts.
