Dallas has lost three straight and eight of 13, including a 119-118 defeat at Miami on Friday, to fall into sixth place in the conference, two games behind Memphis with 10 to play.
The Mavericks have struggled defensively throughout their slide, losing 10 of the 11 games in which they allowed 100 points or more.
“The only thing we can do is play the next 10 as well as we can,” Dallas forward Dirk Nowitzki said. “Right now we’re in sixth place and we’d probably get the Lakers (in the first round). That would be a tough task for us.”
Even though the Mavericks’ next game is against the team with the worst record in the league, they have had little success on the road of late, losing nine of their last 10 away from American Airlines Center.
“We’ve got a lot of talent on this team, and we’ve got to find a way to win,” Dallas center Shawn Bradley said.
Dallas swingman Michael Finley, listed as day to day with a strained right calf, has missed the last two games.
The Mavericks have also lost five straight at Orlando, dating to Dec. 2, 1996.
The Magic are coming off their seventh straight loss, 107-92 to Indiana on Friday night.
NBA leading scorer Tracy McGrady missed the game with tendinitis in his left knee, and remains day-to-day.
According to the Elias Sports Bureau, if Orlando continues playing at its current pace and McGrady wins the scoring title, the Magic would have the second-lowest winning percentage for a team with a scoring champion. The 1952-53 Philadelphia Warriors went 12-57 (.174) despite Neil Johnson’s scoring title.
