As the Celtics face the Dallas Mavericks for the second and final time this season, they will be without starters Jaylen Brown (eye) and Marcus Morris (knee), and will rely on Marcus Smart and Aron Baynes to start in their place. With the Mavericks winning 4 of their last 6 since taking Boston to overtime just over two weeks ago, the matchup should be much better than expected from a last place team. In injury news, Steph Curry and Devin Booker join a growing list of studs heading to the pine for a few weeks.
