(San Antonio, TX) -- LaMarcus Aldridge and Mo Williams will each miss multiple games for the Portland Trail Blazers. Results of MRIs conducted on both players were announced yesterday. Team officials say Aldridge is out with a lower-back contusion that he suffered against San Antonio Wednesday night, and Williams is nursing a right-hip strain he suffered during the Memphis game. Williams is expected to be sidelined for at least the next two weeks, while Aldridge will likely miss the next two games.
