Coach Mike Brown was leaning toward starting Jamison before Hickson came down with flu-like symptoms Tuesday morning. Hickson did not play.
The Cavaliers traded center Zydrunas Ilgauskas to Washington for Jamison as part of a three-team deal last week. Brown eased Jamison into the rotation by bringing him off the bench the first two games.
Brown also confirmed forward Leon Powe has been medically cleared to play. Powe has missed all season while recovering from knee surgery.
