The Trail Blazers took two steps to address their shortage of big men Monday, with center Marcus Camby returning to practice and the team holding a workout of three free agent post players. Camby, who missed the Blazers' last two games after injuring his neck in a fall against Golden State six days ago, returned to practice and worked with the first unit. Camby said his neck was "still sore," but he intends to play Tuesday in Portland's home game against Memphis. "It felt good," Camby said of the practice. "My legs are fine getting down the court." Camby's absence forced the Blazers to go with a small starting unit, with LaMarcus Aldridge playing center and Gerald Wallace at power forward. The Blazers' only other true inside player is rookie Chris Johnson. The team apparently took a step to address that inside shortage, holding a workout involving three post players with NBA experience. They included Robert Swift, who played for Blazers coach Nate McMillan with the Seattle SuperSonics; Earl Barron, who played three seasons for Miami and has also had stints with New York, Phoenix and Milwaukee; and Dwayne Jones, who played for Cleveland, Boston, Charlotte and Phoenix.
