Records: Rockets 13-8; Hawks 12-7.

Key matchup: Josh Smith versus Carl Landry: They won't begin the game against one another, with Luis Scola starting, but will offer an interesting matchup of quick, athletic power forwards. Smith has averaged 14.3 points and 7.7 rebounds in the three games since coming back from a sprained ankle.

Hawks update: Al Horford has been on a roll, shooting 62 percent in his past nine games, but is questionable with a sprained ankle suffered Saturday in Dallas. The Hawks had won four of five games before losing by two in Dallas after a comeback from a 19-point deficit fell short. The Hawks are third in the NBA in 3-point shooting percentage; the Rockets are third in 3-point shooting defense.

Rockets update: The Rockets have a nine-game winning streak against the Hawks in Houston, despite splitting the season series for three consecutive years before last season's sweep. Ron Artest, who did not play Monday in Memphis, is questionable with a sprained right ankle.
