About the Mavs: The Mavericks already have a win in Houston this season, having taken a 137-123 win on Nov. 24 . . . They will be without Luka Doncic and his 28.8 points per game. Doncic suffered a right ankle sprain on Thursday at practice and will miss at least this game and perhaps the second half of the back-to-back Saturday against Atlanta, pending the outcome of an MRI on Saturday.
