Pelicans spokesman Matt Ryan says Davis, who is coming off career highs of 40 points and 21 rebounds in a victory over Boston on Sunday, has an upper respiratory infection.
Valanciunas had been listed as questionable with a sprained lower back, and coach Dwane Casey says the 6-foot-11 center is unable to play in New Orleans.
Valanciunas has played in 66 games this season, averaging 10.5 points and 8.4 rebounds in 27.3 minutes per game.
