Gordon is missing his third straight game with left knee tendinitis that began to limit his play last Friday night in Atlanta. Roberts is sidelined by a bone bruise in his left knee and Rivers has an upper respiratory infection.
Gordon, a starter, is averaging 15.4 points. Roberts, who averages 9.5 points, has started at point guard since Jrue Holiday went out for the season with a stress fracture in his right shin on Jan. 10.
Rivers' absence means he'll miss a chance to play against the team coach by his father, Doc Rivers.
