DALLAS, Dec. 20 (UPI) -- Matt Harpring scored 19 points Friday night as the Utah Jazz posted a 93-81 victory over Dallas in a game that saw both Mavericks Coach Don Nelson and assistant Donn Nelson ejected in the second half.
It was the first loss of the season at home for the Mavericks, who had won their first 12 at the American Airlines Center. Utah snapped a four-game losing streak by holding the Mavericks to just 33 percent shooting.
Don Nelson picked up his first technical foul with 4:22 left in the third quarter and was ejected with his second just under a minute later. His son, who took over the coaching duties, got his first technical early in the fourth quarter and his second with 5:21 remaining.
Donn Nelson stormed onto the court to argue with referee Michael Smith before being escorted to the locker room.
That left the Mavericks in the hands of Del Harris, who watched the team make a brief run, cutting a 17-point deficit to 87-79 on Dirk Nowitzki's driving layup with 2:18 left. But Dallas got no closer.
Utah's Calbert Cheaney scored seven of his 18 points in the decisive third quarter.
Mark Jackson's layup capped a 7-0 run that made it 67-52 with 2:39 to go in the period. Jackson's breakaway layup gave Utah its biggest cushion, 74-57, with 31 seconds left.
Nowitzki scored 28 points and Steve Nash added 25 for the Mavericks.
