Beal, Washington's leading scorer, is active Tuesday night, but listed as doubtful. Gary Neal replaces him in the lineup.
The Wizards also say Nene is listed as doubtful because of back spasms.
Beal hurt his shoulder in Washington's previous game, a 114-99 loss at the Atlanta Hawks on Saturday. He was held to a season-low 11 points and committed eight turnovers in that game.
Beal is averaging 22.7 points this season.
