NO TIMETABLE FOR SMITH
Dennis Smith Jr. missed his second straight game with a left hip strain, and Mavericks coach Rick Carlisle didn't have a timeframe on when his rookie point guard might be able to return. Smith is going back to Dallas to see a doctor.
"He's getting a little better each day, but I'm not going to give you any timetables right now," Carlisle said. "Him being 100 percent healthy is the No. 1 priority. That's what's got to be our focus."
Smith, the No. 9 pick in the draft, is averaging 14.4 points and 4.0 assists per game.
