Gordon left Saturday night's 108-104 victory over New Orleans in the fourth quarter with a bruise. He had scored 21 points in 27 minutes for the Rockets before exiting the court with a limp.
The Rockets have won nine of their past 10 games.
Gordon's role has been amplified with the absence of Chris Paul, who is expected to miss at least two more weeks with a hamstring injury.
Gordon, 30, is averaging 15.5 points a game.
