The Dallas Mavericks (39 - 20) defeated the Toronto Raptors (37 - 19) 99 - 92 Tuesday at the American Airlines Center. Dallas' Rajon Rondo took the ball up the floor with the Mavericks losing by nine early in the third quarter. Coach Rick Carlisle took a timeout and Rondo never got back on the floor after the two appeared to have a heated exchange. After Rondo's exit, the Mavericks outscored 46 - 30 to close out the Raptors and notch their 39th win of the season. The reason behind Rondo and Carlisle's spat was unclear, but the Mavericks will hope that those tensions are resolved sooner rather than later. Toronto mustered just 15 points in the fourth quarter as its losing streak extended to three games. DeMar DeRozan led the team in scoring with 18 points and Greivis Vasquez had a quality game off the bench with 14 points on 5 - of - 6 shooting from the field. The Raptors have another tough test ahead of them with a matchup against Golden State scheduled for Friday. Dallas got key performances in the second half from Devin Harris and J.J Barea, who split the minutes at point guard in Rondo's absence. They combined for 27 points, eight assists, and four rebounds over 47 total minutes in the game. The Mavericks shot 48 percent from the field as a team on their way to their third straight game. Tyson Chandler was shaken up towards the end of the game, but it did n't appear to be serious. The Mavericks will play the second half of a back - to - back Wednesday against the Hawks.
